Description

[Technical Field]

[0001] The present invention relates to a marking aid and a marking work set, and more particularly to a marking aid and a marking work set that can reliably fix the marking point and allow one person to easily mark it out.

[0002] At construction sites for architectural and civil engineering works, marking out information from design drawings at the actual construction site by using ink to mark lines and dimensions on the ground, walls, pillars, etc. is called marking out work (hereinafter referred to as "marking out"). Marking out is an important task in terms of maintaining construction quality, improving construction efficiency, and improving construction accuracy, and is carried out in all processes, including site surveying, foundation work, framework work, finishing work, piping work, and electrical work. For marking, a marking device is used that has a main body with a built-in ink pot, an ink thread that can be pulled out from the main body through the ink pot, and a marker attached to the tip of the ink thread. In detail, the needle of the marker is fixed at one point on the work surface, and the main body of the device is placed at another point on the work surface, and by pulling up and flicking the ink thread with a finger, a reference line for construction is drawn between the two points using the ink that has soaked into the ink thread. However, when marking out on a concrete surface, it is not possible to fix the karco with a needle like in wooden buildings and work alone, so marking out usually requires a pair of people. For this reason, in order to improve workability, technology has been developed that does not require a pair of people and allows marking out by one person. Patent documents 1 to 3 disclose an ink thread fixing jig that can fix the point by locking the karuko and applying the load of the jig. Non-patent document 1 discloses a method for marking by one person by inserting and fixing the karuko needle into the side of the shoe and pressing the ink thread with the sole of the shoe.

[0005] The conventional technology has the following problems. <1> The ink thread fixing jigs in Patent Documents 1 to 3 are configured to fix the ink thread using only the weight of the jig, so when the ink thread is flicked, the jig is pulled by the ink thread, which can cause the jig to move and shift the marking point. <2> In the marking method described in Non-Patent Document 1, it is difficult to securely hold the ink thread with the sole of the shoe, and when the ink thread is pulled up with the fingers, it is guided into the groove in the sole, which can cause the marking point to shift (Figure 5).

[0006] SUMMARY OF THE INVENTION An object of the present invention is to provide a marking aid and a marking work set that solves the above-mentioned problems of the prior art. [Means for solving the problem]

[0007] The marking aid of the present invention comprises a band that can be fitted around the toe of a worker's shoe and a retaining material attached to the band, and is characterized in that when the retaining material of the marking device is engaged with the retaining material, the bearing surface of the band covering the sole of the worker's shoe can support and fix the ink thread to the construction surface.

[0008] The marking aid of the present invention may be configured such that the band comprises a stretchable, band-shaped band body and an adhesive piece extending from one longitudinal end of the band body, and the band body is wound around the toe of a worker's shoe and the adhesive piece is attached to the band body, thereby making it possible to attach the band endlessly around the toe of the worker's shoe.

[0009] The marking aid of the present invention may have two adhesive pieces extending from one longitudinal end of the band body, a locking receiving material provided at the other longitudinal end of the band body, and when the band is attached endlessly around the toe of a worker's shoe, the locking receiving material may be exposed on the surface of the band between the two adhesive pieces.

[0010] The marking work set of the present invention is characterized by comprising a marking device having a main body with a built-in ink pot, an ink thread that can be pulled out from within the main body, a karko provided at the tip of the ink thread, and a locking material connected to the karko, and a marking auxiliary tool, and the locking material is locked to a locking receiving material.

[0011] In the marking work set of the present invention, one of the locking material and the locking receiving material may be a carabiner, and the other of the locking material and the locking receiving material may be a rod-shaped body, ring-shaped body, or loop-shaped body capable of locking the carabiner. [Effects of the Invention]

[0012] The marking aid and marking work set of the present invention uses the bearing surface of the belt wrapped around the sole of the worker's shoe to support and fix the ink thread in a planar manner on the construction surface, preventing the point of the ink thread from shifting, allowing accurate and easy marking by one person.

[0014] The marking aid and marking work set of the present invention will be described in detail below with reference to the drawings. In this specification, the term "working surface" refers to the surface on which a reference line is drawn with ink. The terms "surface," "outer surface," and "inner surface" of the band refer to the respective surfaces of the band when it is wrapped around a worker's shoe. [Example]

[0015] <1> Marking work set (Figure 1) The marking work set 1 of the present invention is a work set for marking. The marking work set 1 includes at least a marking auxiliary tool 10 and a marking device 20. The marking work set 1 allows a worker to easily and accurately perform marking work by attaching the marking auxiliary tool 10 to the worker's shoe A and manually operating the marking device 20 without needing a serial number. A detailed method of using the marking work set 1 will be described later.

[0016] <2> Marking aid (Figure 2) The marking auxiliary tool 10 is a tool that assists marking by the marking device 20. The marking aid 10 includes at least a band 11 and a locking member 12 provided on the band 11. The marking aid 10 is used by wrapping a band 11 around the toe of a shoe A of a marking worker and engaging a locking member 24 of the marking device 20 with an engaging receiving member 12. One feature of the marking aid 10 is that the support surface 11c at the bottom of the band 11 can support and fix the marking thread 22 in a planar manner on the construction surface.

[0017] <2.1> Band The band 11 is a member that is wrapped around the toe of the worker's shoe A and fixed in place. The band 11 includes a stretchable band body 11a and an adhesive piece 11b provided on the band body 11a. The band body 11a has a smooth surface, and when the band 11 is attached to the worker's shoe A and the worker steps on the band body 11a with the sole A1, a smooth bearing surface 11c is formed on the bottom of the band body 11a. In this example, a strip-shaped rubber band is used as the band body 11a, but the material of the band body 11a is not limited to rubber and may be elastomer resin, silicone resin, or the like.

[0018] <2.1.1> Adhesive fragments The adhesive piece 11b is a member for holding the band body 11a in an endless state. In this example, two strips extending longitudinally from the ends of the band body 11a are used as the adhesive pieces 11b. A male surface (or female surface) of a hook-and-loop fastener is attached to the outer surface of the attachment piece 11b as attachment means, and a female surface (or male surface) of a hook-and-loop fastener is attached to the outer surface of the band body 11a corresponding to the attachment piece 11b. However, the configuration of the adhesive piece 11b is not limited to the above, and for example, the number of adhesive pieces 11b may be one or three or more. Also, the attachment means is not limited to a hook-and-loop fastener, and may be a string, a belt buckle, a snap button, or the like.

[0019] <2.2> Locking receiving material The locking member 12 is a member for connecting to a locking member 24 of the marking device 20 . In this example, the locking member 12 is provided at the center of the edge of the band body 11a opposite the adhesive piece 11b. More specifically, both widthwise ends of the edge of the band body 11a protrude outward in the longitudinal direction, and both ends of a metal pin extending widthwise are held between the protruding parts. By engaging a locking member 24 (described later) with the pin of the locking receiving member 12, the karuko 23 can be connected to the marking auxiliary tool 10. However, the configuration of the locking member 12 is not limited to the above, and it may be a metal ring or loop string attached to the surface of the band 11.

[0020] <3> Marking device (Figure 3) The marking device 20 is a main device for marking. The marking device 20 comprises a device body 21 with a built-in ink pot, an ink thread 22 that can be drawn out from the device body 21 through the ink pot, a karko 23 attached to the tip of the ink thread 22, and a locking member 24 connected to the karko 23. Before use, the ink thread 22 is stored in the device body 21, and the calco 23 is fixed to the tip of the device body 21. When in use, the calco 23 is pulled to pull the ink thread 22 out of the device body 21. At this time, ink from the ink pot adheres to the ink thread 22. The locking member 24 is a member that locks and connects the karuko 23 to the marking auxiliary tool 10. In this example, a carabiner attached to the karuko 23 is used as the locking member 24. However, the locking member 24 is not limited to a carabiner and may be, for example, a hook metal fitting.

[0021] <4> How to use the marking work set (Figure 4) The marking aid 10 is fixed to one of the worker's shoes A. Specifically, the band body 11a is wrapped around the toe of the worker's shoe A, and while pulling the band body 11a, the adhesive piece 11b is attached to the outer surface of the band body 11a, thereby tightening and fixing the shoe A with the band 11. At this time, it is desirable to face the locking receiving member 12 toward the outside of the shoe A (the outside of the body). The karuko 23 of the marking device 20 is pinched to pull out the marking thread 22, and the locking member 24 is connected to the locking receiving member 12. The ink thread 22 is extended from the outside of the shoe A through the sole A1 to the inside of the shoe A. At this time, the ink thread 22 is aligned with a first point on the application surface, and by applying weight to the shoe A, the ink thread 22 is pressed against the application surface by the pressure bearing surface 11c of the sole A1 and securely fixed in place. This prevents the point from shifting when the ink thread 22 is flipped. The fingers of one hand are hooked around the middle of the ink thread 22 extended from the sole A1, and the device body 21 is grasped with the other hand and pressed against the second point on the application surface. The device body 21 is operated to tension the ink thread 22, and the finger that has been placed on the ink thread 22 is flicked to adhere the ink from the ink thread 22 to the surface to be worked, thereby drawing a reference line. [Example]

[0022] [Example in which the band is a tube body] In the first embodiment, the band 11 of the marking auxiliary tool 10 is a strip-shaped body, but the present invention is not limited to this. In this example, the band 11 is made of an endless rubber tube. In detail, a rubber tube corresponding to the outer diameter of the shoe A is cut to the required width of the band 11, and the locking member 12 is attached to the outer surface of the band 11. When using the marking aid 10, the toe of the worker's shoe A is inserted into the loop of the rubber tube, and the shoe A is tightened from the outside by the elastic force of the rubber, thereby fixing the marking aid 10 to the shoe A. [Example]

[0023] [Example of swapping the locking material and locking receiving material] In the first embodiment, the marking auxiliary tool 10 is provided with the locking receiving member 12, and the marking device 20 is provided with the locking member 24, but the present invention is not limited to this. In this example, a locking member such as a carabiner or hook is provided on the band 11 of the marking auxiliary tool 10, and a ring-shaped locking receiving member is provided on the karuko 23 of the marking device 20. The key point is that the structure must be such that the karuko 23 can be connected to the marking auxiliary tool 10 by combining the locking member and the locking receiving member.
