Description

[Technical field]

[0001] The present invention relates to a cutting line marking device that traces the unevenness of a wall surface at a construction site or the like to draw a cutting line for a floor covering. [Background technology]

[0002] When installing overlays on the parts of houses and vehicles where the wall and floor meet, there are pillars, ducts, and other objects that protrude into the floor, as well as various curved and bent parts on the wall. In order to install the overlay flooring material on such parts so that it comes into contact with the wall without any gaps, the end of the flooring material on the wall side must be cut accurately to fit the shape of the wall. Traditionally, flooring materials would be cut by skilled craftsmen using their many years of experience to estimate the dimensions, and in some cases they would make adjustments on-site to fit the material.

[0003] However, this method had several issues, such as a) variation in construction precision, b) low work efficiency, c) high material waste, and e) difficulty in training skilled workers because it relies on the skills of experienced craftsmen. To solve this problem, for example, Patent Document 1 provides a "floor guide marker." However, the floor guide marker of Patent Document 1 is designed to grasp the gripping part 1 of the floor guide marker M placed on the floor material F to be marked, which is laid along the wall surface W, and to abut the tip 3 of the sliding rod 2 against the wall surface W, and to draw the gripping part 1 approximately parallel to the wall surface W, and to mark the left-side inside corner of the pillar H as it is. Although the gripping part 1 and the sliding rod 2 maintain a right angle, there are concerns about whether the gripping part 1 can be moved while maintaining its parallelism with the wall surface, which is the key point. For this reason, [Claim 1] and paragraph number of Patent Document 1

[0004] The use of the term "approximately parallel" in the Furthermore, the marker lines are made with marking screws, so there are still problems with the accuracy of the lines.

[0004] Furthermore, in recent years, technology has been developed that uses laser measuring devices and 3D scanners to accurately measure the shape of a wall surface and then automatically cuts flooring materials based on that data (patent documents not included). However, these devices are expensive due to their high functionality, and it takes time to learn how to operate them, which means they lack simplicity and ease of use in the field.

[0006] SUMMARY OF THE PRESENT DISCLOSURE In view of the above problems, the present invention provides a cutting line marking device which has a simple structure while ensuring accuracy and which is easy to carry and handle. [Means for solving the problem]

[0007] In order to solve the above problems, the cutting line marking device according to the present invention is configured as follows.

[0008] That is, a substrate having at least two perpendicular sides and an edge portion of one of the perpendicular sides of the substrate Along A sliding protrusion formed on the back side that abuts against and slides on the end surface of the long veneer to be cut; a slide marking means disposed along a side perpendicular to the sliding protrusion; It is equipped with

[0009] The slide marking means includes a slide guide attached along the edge of the substrate, and a slider that engages with the slide guide and extends linearly from the substrate; The slider is provided with Marking hole for attaching marker and, It is characterized by being composed of

[0010] The engagement between the slide guide and the slider is characterized in that the slide guide is a linearly formed convex or concave stripe and the slider engages with the slide guide.

[0011] Furthermore, the slide guide is characterized in that it can be attached and detached by being inserted and removed through an opening of the slide guide which is open at one or both ends.

[0012] The slide guide is not limited to being provided on only one side of the substrate, but may be provided on each of two opposing sides of the substrate perpendicular to the sliding protrusion. Effect of the Invention

[0013] With the above configuration, the sliding protrusion protruding from the back side of the board is brought into contact with the edge of the long veneer to hold the position, and the tip of the slider is brought into contact with the unevenness of the wall surface, and the slide marking means marks the amount of protrusion of the unevenness of the wall surface toward the floor surface as the distance from the edge of the long veneer. Then, while maintaining this state, the sliding protrusion of the board is slid along the edge of the wood, so that the trajectory of the marker movement can be drawn as a continuous line on the top surface of the long veneer. This allows the cutting line of the covering member to be obtained in the unevenness of the floor surface. [Brief description of the drawings]

[Figure 6] FIG. 2 is a perspective view showing the state of use of the present embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] The present embodiment will be described in detail with reference to the drawings. <Board configuration>

[0016] The reference numeral 1 in the figure denotes a substrate constituting the main body of this embodiment. The substrate 1 is formed in a rectangular shape with four perpendicular sides. The surface of the substrate 1 is formed to be smooth so that it can slide freely on the surface of a long piece of veneer (hereinafter referred to as "long piece of veneer") 2 to be cut.

[0017] A sliding protrusion 10 protruding toward the lower surface side is formed on the edge of one side of the substrate 1. This sliding protrusion 10 is formed continuously along the edge with a predetermined length, but is not limited to this and may be formed in two or more places with a predetermined interval between them.

[0018] With this configuration, the sliding protrusion 10 functions as a positioning member for sliding in the longitudinal direction of the base plate 1 by coming into contact with the end face 20 (the side face in the width direction of the long veneer board) of the long veneer board 2 . <Configuration of slide marking means>

[0019] Slide marking means 3 is provided on the side of substrate 1 perpendicular to the side on which sliding convex portion 10 is provided. In this embodiment, slide marking means are provided on two parallel opposing sides, but providing slide marking means on only one side is also within the scope of the concept of the present invention.

[0020] The slide marking means 3 is composed of a guide groove 30 as a slide guide provided along the edge of the substrate 1, and a slider 31 in the form of a long ruler that engages with the guide groove 30 and slides.

[0021] The slider 31 has a guide rib 31a with an L-shaped cross section formed along its upper surface in the longitudinal direction, and this guide rib 31a slidably engages with a guide groove 30 whose cross section is U-shaped with an opening downward and part of the opening edge is hook-shaped. Both ends of the guide groove 30 are open, and the guide rib 31a is inserted from the opening.

[0022] The slider 31 has sharp ends 31b at both ends thereof. The slider 31 has a top surface on which a plurality of marker openings 31c are formed in a row along the length direction. <Function of the Example>

[0023] With the above configuration, the operation of this embodiment is as follows: first, the guide rib 31a of the slider 31 is inserted from the open portion 30a at one end of the guide groove 30, so that the slider 31 can slide freely within the guide groove 30. In this state, when the sliding protrusion 10 of the base plate 1 is brought into contact with the end wood surface 20 of the long veneer 2 to be cut and held in position, the sliding direction of the slider 31 (arrow X) becomes perpendicular to the end wood surface 20 and perpendicular to the wall surface W.

[0024] Here, the tip 31b of the slider 31 is brought into contact with the uneven portion P protruding from the wall W toward the floor F, and a mark is made with a marker 32, such as a pencil, ballpoint pen, or nail, attached to the marking opening 31c formed in the slider 31. Then, while keeping the marker 32 pressed, the board 1 is moved lengthwise along the end surface 20 of the long veneer 2 (arrow Y). At the same time, the tip 31b of the slider 31 is appropriately slid to keep it in contact with the uneven portion P from the wall W.

[0025] This creates a synergistic effect between the lateral movement (arrow X) of the slider 31 relative to the long veneer board 2 and the vertical movement (arrow Y) of the base plate 1, and the movement trajectory of the marker 32 attached to the marking opening 31c of the slider 31 is drawn on the surface of the long veneer board 2 as a line 4 that traces the unevenness P from the wall surface W. By cutting the long veneer board 2 along this tracing line 4, it is possible to form a covering material for the floor surface that fits without gaps to the unevenness P protruding toward the floor surface. <Other Examples>

[0026] In the above embodiment, the slide marking means 3 is attached to one side of the substrate 1, but it may be provided on each of the two sides of the substrate 1 perpendicular to the sliding protrusion 10, so that the slider 31 can be attached to either of the two guide grooves 30 according to the condition of the wall surface W. For example, when the guide groove 30 of the substrate 1 is moved to an inside corner of the wall surface W, the slider 31 attached to the guide groove 30l on the left side facing the wall surface W can be removed and attached to the guide groove 30r on the right side for use, thereby tracing until it abuts against the wall surface W at the inside corner.

[0027] Furthermore, the sliding protrusions 10 may be formed on both the lower and upper surfaces of the substrate 1. This allows the substrate 1 to be used upside down. When only one side is used, a gripping member 11 may be provided on the upper surface to facilitate movement of the substrate, if necessary (see FIG. 1). [Explanation of symbols]
