Description

[Technical field]

[0001] The present invention relates to a positioning tool and a convex rule with a positioning tool. [Background technology]

[0002] In the early stages of civil engineering work, workers measure the elevation and clarify the elevation position on the ground by driving nails into the sides of piles driven into the ground as markers for the elevation position based on the measurement results (see non-patent document 1). Generally, the height of the pile is at most about the height of the worker's knees, that is, about 50 cm, and the nail is driven into the pile at a height of, for example, 5 cm to 15 cm from the ground. This process is, for example, as follows: (1) the worker hooks the prongs of the measuring tape of the convex rule held in one hand onto the top end surface of the pile while running the measuring tape along the side of the pile, (2) brings the worker's eye close to the target position and makes a dent (temporary mark) at the target position with the nail held in the other hand, and (3) replaces the convex rule held in one hand with a hammer, and while the tip of the nail held in the other hand is placed against the temporary mark, the nail is driven into the target position of the pile (fixed).

[0015] <Overview> Hereinafter, several embodiments and several modified examples will be described. In the description of the second and subsequent embodiments and several modified examples, when describing components having the same or similar functions as components described in the previous embodiment, etc., please note that the same reference numerals as those in the previous embodiment, etc. will be used and the description will be omitted as appropriate.

[0016] First Embodiment The function, configuration, usage, and effects of the convex rule with positioning tool 20 (see FIG. 1) of the first embodiment will be described below. In the following description, the convex rule will be abbreviated as CR. Also, the convex rule with positioning tool will be abbreviated as ACR. Therefore, the convex rule with positioning tool 20 will be abbreviated as ACR20.

[0017] <Function and configuration of ACR in the first embodiment> Fig. 1 is a schematic diagram for explaining a method for measuring a target position of a pile and driving a nail into the target position using the ACR 20. Fig. 2A is a partially enlarged view of the ACR 20. Fig. 2B is a cross-sectional view taken along the line 2B-2B of Fig. 2A. As shown in FIG. 1, the ACR 10 includes a CR 10 and a positioning tool 100.

[0018] [CR] As shown in FIG. 1, the CR 10 includes a main body 12, a measuring tape 14, and a claw 16. The main body 12 is box-shaped and houses the measuring tape 14 wound inside. The measuring tape 14 is a magnetic metal tape, and its cross section is formed in an arc shape (see FIG. 2B). The measuring tape 14 has a scale on its surface (see FIG. 1 and FIG. 2A), and the surface is a concave surface (its reverse surface is a convex surface). The claw 16 is fixed to the tip of the measuring tape 14, and forms a perpendicular surface with respect to the measuring tape so that it can be hooked on a reference position (end surface) of the object to be measured (a stake in the example of FIG. 1).

[0019] [Positioning tool] As shown in Figures 1, 2A and 2B, the positioning tool 100 is attached to a measuring tape 14 and is used to fix a nail (not shown, an example of a shaft) at a target position on a pile. Here, the target position in the example of Figure 1 is the position where the scale of the measuring tape 14 is 13.6 (cm). As shown in FIGS. 2A and 2B, the positioning tool 100 includes a curved plate 110, a protruding portion 120, and a pressing portion . The curved plate 110, the protruding portion 120, and the pressing portion 130 are, for example, elastic bodies made of resin that are integrally formed. In addition, the resin that constitutes the curved plate 110, the protruding portion 120, and the pressing portion 130 has transparency, for example. Here, having transparency means that when placed over the surface of the measuring tape 14, it has enough light transmittance to allow the user to visually recognize the scale.

[0020] (Curved plate) The curved plate 110 is rectangular in plan view (seen in the thickness direction) (see FIG. 2A), and has a circular cross section (see FIG. 2B). As shown in FIG. 2B, the curved plate 110 has a shape that contacts the back surface of the measurement tape 14 when the positioning tool 100 is attached to the measurement tape 14 (when attached). More specifically, the curved plate 110 is arranged so that its recessed surface side contacts the back surface of the measurement tape 14 and protrudes from both ends of the measurement tape 14 in the width direction (see FIGS. 2A and 2B). The radius of curvature of the curved plate 110 is set smaller than the radius of curvature of the measurement tape 14 (see FIG. 2B).

[0021] (Protruding part) The protruding portion 120 is connected to the curved plate 110 via the pressing portion 130, and is a portion of the flat plate that protrudes from the measurement tape 14 to the outside in the width direction of the measurement tape 14 when attached (see FIG. 2A and FIG. 2B), and is a portion in which at least one notch 122 into which a nail (not shown) is fitted is formed. In this embodiment, the number of at least one notch 122 is one as an example, and the notch 122 is formed so that the width gradually narrows from the outside to the inside in the width direction of the measurement tape 14. Specifically, the shape of the notch 122 is V-shaped. From another perspective, the protruding portion 120 can be said to be a flat plate in which a V-shaped notch 122 is formed in the center in the length direction of a rectangular flat plate narrower than the curved plate 110 in a plan view.

[0022] (Pressing part) The pressing part 130 is a rectangular flat plate in a plan view (seen in the thickness direction) (see Figs. 2A and 2B). The pressing part 130 is disposed facing the surface of the measurement tape 14. The pressing part 130 is connected to the curved plate 110 at one end in the width direction of the measurement tape 14, and is connected to the protruding part 120 at the other end (see Fig. 2B). The boundary between the pressing portion 130 and the curved plate 110 and the surrounding area are bent, and the pressing portion 130 sandwiches the measurement tape 14 between the curved plate 110. When the positioning tool 100 is in a standalone state (without sandwiching the measurement tape 14), the pressing portion 130 faces the recessed surface of the curved plate 110. In contrast, the pressing portion 130 and the protruding portion 120 each form a flat surface that is an extension of the other. The bent portion BP (see FIG. 2B) at the boundary between the pressing portion 130 and the curved plate 110 and the vicinity thereof constitutes a leaf spring for pressing one of the pressing portion 130 and the curved plate 110 against the other. Therefore, the pressing portion 130 has a function of pressing the curved plate 110 against the measurement tape 14 by using the leaf spring while contacting both ends of the measurement tape 14 in the width direction with its back surface.

[0023] The above is a description of the function and configuration of the ACR 20 in the first embodiment.

[0024] <How to use the ACR of the first embodiment> Next, a method of using the ACR 20 of the first embodiment, specifically, a method of using the ACR 20 to measure a target position of a pile (see FIG. 1) and drive a nail into the target position, will be described with reference to FIG.

[0025] First, a worker drives a stake into the ground. Next, the worker performs a horizontal survey using a surveying tool (not shown), which clarifies the target position for driving the nail into the stake. Next, the operator pulls out the measuring tape 14 from the main body 12. Then, the operator aligns the tip PE of the notch 122 of the positioning tool 100 with the target position (moves the positioning tool 100 from a position other than the target position to the target position). Next, while holding the ACR 20 in one hand, the worker hooks the claw 16 of the ACR 20 onto the top end (upper surface) of the pile and runs the measuring tape 14 along the side of the pile. Then, the worker fits a nail held in the other hand into the notch 122 and makes a contact mark on the pile with the tip of the nail. Finally, the worker replaces the ACR20 held in one hand with a hammer (not shown), aligns the nail held in the other hand with the contact mark again, and drives the nail into the pile with the hammer, completing the method of driving the nail into the target position.

[0026] The above is a description of how to use the ACR 20 of the first embodiment.

[0027] <Advantages of the First Embodiment> Next, the effects of the first embodiment will be described.

[0028] [First effect] As shown in FIGS. 1, 2A, and 2B, the positioning tool 100 of the first embodiment includes a curved plate 110, a protruding portion 120, and a pressing portion . The curved plate 110 has a cross section that is arc-shaped, and when attached, its concave surface comes into contact with the back surface of the measurement tape 14. The pressing unit 130 presses the curved plate 110 against the measurement tape 14 by using a leaf spring while contacting both ends of the measurement tape 14 in the width direction with its back surface. With the above configuration, the curved plate 110 is attached to the measurement tape 14 so as not to move. In addition, the protruding portion 120 protrudes from the measuring tape 14 on the outer side in the width direction of the measuring tape 14 when the measuring tape 14 is attached (see FIG. 2A and FIG. 2B), and has a V-shaped notch 122 into which a nail (not shown) fits. With the above configuration, the tip PE of the V-shaped notch 122 serves as a marker for the position of the notch 122. Therefore, the positioning tool 100 of the first embodiment can facilitate positioning of the nail when the target position of the pile is measured and the nail is fixed using the CR 10. Accordingly, the ACR 20 of the first embodiment can facilitate positioning of the nail when the target position of the pile is measured and the nail is fixed.

[0029] [Second Effect] In the first embodiment, the curved plate 110, the protruding portion 120, and the pressing portion 130 are an integrally formed elastic body made of resin. The pressing portion 130 faces the recessed surface of the curved plate 110, and sandwiches the measurement tape 14 between the curved plate 110 and the pressing portion 130 when attached (see FIG. 2B). Therefore, when the positioning tool 100 of the first embodiment is used to measure the target position of the pile and fix the nail using the CR10, it elastically deforms and is attached to the measuring tape 14 in a state aligned with the longitudinal direction of the measuring tape 14 so as not to move.

[0030] The above is a description of the effects of the first embodiment. Also, the above is a description of the first embodiment.

[0031] Second Embodiment Next, the function, configuration, usage method, and effects of the ACR 20A (see Figs. 3A and 3B) of the second embodiment will be described. Here, only the parts of the second embodiment that are different from the first embodiment will be described.

[0032] <Function, configuration and usage method of ACR in the second embodiment> Fig. 3A is a partially enlarged view of the ACR 20A. Fig. 3B is a cross-sectional view taken along line 3B-3B of Fig. 3A. As shown in Figs. 3A and 3B, the ACR 20A includes a CR 10 and a positioning tool 100A. The positioning tool 100A of the second embodiment includes a pressing portion 130A instead of the pressing portion 130 (see FIGS. 2A and 2B) of the first embodiment. Unlike the pressing part 130 in the first embodiment, the pressing part 130A does not cover the entire surface of the measurement tape 14, but covers only one end of the measurement tape 14 in the width direction. The positioning tool 100A is attached to the measurement tape 14 by clamping the end of the measurement tape 14 in the width direction at the bent part BP while pressing it.

[0033] <Effects of the second embodiment> The effects of the second embodiment are basically the same as those of the first embodiment.

[0034] The above is a description of the second embodiment.

[0035] Third Embodiment Next, the function, configuration, usage method, and effects of the ACR 20B of the third embodiment (see Figs. 4A, 4B, and 4C) will be described. Here, only the parts of the third embodiment that are different from the first embodiment will be described.

[0036] <Function and configuration of ACR in the third embodiment> Fig. 4A is a partially enlarged view of the ACR 20B, Fig. 4B is a cross-sectional view taken along line 4B-4B in Fig. 4A, and Fig. 4C is a cross-sectional view of the ACR 20B when the positioning tool 100B is set at the positioning position. As shown in Fig. 4A and Fig. 4B, the positioning tool 100B of the third embodiment includes a pair of protruding portions 120 on both widthwise outer sides of the pressing portion 130. Here, one protruding portion 120 is referred to as a first protruding portion 120B1, and the other protruding portion 120 is referred to as a second protruding portion 120B2. The first protruding portion 120B1 and the second protruding portion 120B2 each have a symmetrical shape on both sides of the pressing portion 130 in the width direction. The configuration of the first protruding portion 120B1 is basically the same as that of the protruding portion 120 of the first embodiment. Moreover, the positioning tool 100B (see FIGS. 4A and 4B) includes a curved plate 110B instead of the curved plate 110 of the first embodiment. The curved plate 110B has a width ranging from the opening end of the notch 122 in the first protruding portion 120B1 to the opening end of the notch 122 in the second protruding portion 120B2. One end of the curved plate 110B is connected to one end of the second protruding portion 120B1, and the boundary between them forms a bent portion BP. On the other hand, the other end of the curved plate 110B is in linear contact with the opening end of the notch 122 in the first protruding portion 120B1. This contact portion is prevented from opening by, for example, tape (not shown).

[0037] <Method of using ACR according to the third embodiment> As shown in Fig. 4C, the positioning tool 100B of the third embodiment is slid in the width direction of the measuring tape 14 to bring the measuring tape 14 into contact with the end of the positioning tool 100B in the width direction, thereby determining the width direction position. Here, Fig. 4C shows an example in which the measuring tape 14 is brought into contact with the end of the positioning tool 100B on one side in the width direction, but it is also possible to bring the measuring tape 14 into contact with the end on the opposite side (not shown).

[0038] <Effects of the third embodiment> The positioning tool 100B of the third embodiment can be used by determining its position on one side and the other side in the width direction of the measuring tape 14. Therefore, the positioning tool 100B can be set at a position that is easy for an operator to use depending on the location of the pile where the nail is to be driven. Other effects of the third embodiment are basically the same as those of the first embodiment.

[0039] The above is a description of the third embodiment.

[0040] Fourth Embodiment Next, the function, configuration, usage method, and effects of the ACR 20C of the fourth embodiment (see Figs. 5A and 5B) will be described. Here, only the differences between the first embodiment and the fourth embodiment will be described.

[0041] <Function, configuration and usage method of ACR according to the fourth embodiment> Fig. 5A is a partially enlarged view of the ACR20C, and Fig. 5B is a cross-sectional view taken along line 5B-5B of Fig. 5A. The positioning tool 100C of the fifth embodiment (see Figs. 5A and 5B) includes a pressing part 130C instead of the pressing part 130 of the first embodiment (see Figs. 2A and 2B). The pressing part 130C has a curved shape similar to that of the curved plate 110, is a permanent magnet fixed to the convex surface of the curved plate 110, and sandwiches the curved plate 110 with the measuring tape 14 when attached (see Fig. 5B). The curved plate 110 and the protruding part 120 are integrally formed and are non-magnetic elastic bodies made of resin.

[0042] <Effects of the Fourth Embodiment> The positioning tool 100C of the fourth embodiment positions the curved plate 110 on the measurement tape 14 by the magnetic force of the pressing part 130C that sandwiches the curved plate 110 between the measurement tape 14. Therefore, unlike the first to third embodiments, the positioning tool 100C is not attached to the measurement tape 14 using mechanical force (specifically, spring force). Therefore, the positioning tool 100C of the fourth embodiment has higher mechanical durability than the first to third embodiments. Other effects of the third embodiment are basically the same as those of the first embodiment.

[0043] The above is a description of the fourth embodiment.

[0044] <<Multiple Modifications>> As described above, the present invention has been described with reference to the first to fourth embodiments described above, but the forms included in the technical scope of the present invention are not limited to these embodiments. For example, the following multiple modified examples are also included in the technical scope of the present invention. Furthermore, the forms included in the technical scope of the present invention may include those in which a part of the above-mentioned first to fourth embodiments and the multiple modified examples described below are changed to a part of another form.

[0045] <First Modification> 6A is a partially enlarged view of the ACR20D of the first modified example. The positioning tool 100D constituting the ACR20D of the first modified example has the same configuration as the positioning tool 100 (see FIG. 2A) of the first embodiment, and a linear mark LN is printed at the position of the tip PE of the notch 122 from a part of the protruding part 120 to the entire width direction of the pressing part 130. Therefore, positioning is easy by overlapping the mark LN with the graduations of the measuring tape 14. The other effects of the first modified example are similar to those of the first embodiment and the like.

[0046] <Second Modification> 6B is a partial enlarged view of the ACR20E of the second modified example. In the positioning tool 100E constituting the ACR20E of the second modified example, the notch 122 and the mark LN of the positioning tool 100D of the first modified example (see FIG. 6A) are changed to a notch 122E and a mark LNE, respectively. Specifically, the notch 122E is changed from a V-shape to a U-shape, and the mark LNE is printed from a part of the protruding portion 120 to near the center of the pressing portion 130 in the width direction. The effects of the second modified example are similar to those of the first modified example.

[0047] <Third Modification> 6C is a partial enlarged view of the ACR20F of the third modified example. The positioning tool 100F constituting the ACR20F of the third modified example has the same configuration as the positioning tool 100E of the second modified example (see FIG. 6B), and has a notch 122F1 and a mark LNF1, and a notch 122F2 and a mark LNF2 formed on one side and the other side of the notch 122E and the mark LNE in the length direction of the measurement tape 14. The notch 122F1 is, for example, a U-shaped notch wider than the notch 122E, and the notch 122F2 is, for example, a U-shaped notch narrower than the notch 122E. The positioning tool 100F of the third embodiment is formed with three types of notches 122E, 122F1, and 122F2 with different widths. Therefore, compared to the second embodiment, it can accommodate nails with different widths. Other effects of the third modified example are similar to those of the second modified example.

[0048] <Fourth Modification> 6D is a partially enlarged view of the ACR 20G of the fourth modified example. The positioning tool 100G constituting the ACR 20G of the fourth modified example has one notch 122G cut out along the length of the measurement tape 14, instead of the three notches 122E, 122F1, and 122F2 of the positioning tool 100F of the third modified example (see FIG. 6C). When nails of different thicknesses are hammered into the needle, the ACR20G has marks LNE, LNF1, and LNF2 marked according to the position where the nail will be clamped. The effects of the fourth modified example are similar to those of the third modified example.

[0049] <Fifth Modification> 6E is a partially enlarged view of the ACR20H of the fifth modified example. The positioning tool 100H constituting the ACR20H of the fifth modified example is a modification of the ACR20C of the fourth embodiment (see FIG. 5A and FIG. 5B) and the ACR20B of the third embodiment (see FIG. 4A and FIG. 4B). Specifically, the protruding portion 120 of the ACR20C of the fourth embodiment is a pair of protruding portions 120B1 and 120B2, like the ACR20B of the ACR20B of the third embodiment (see FIG. 4A and FIG. 4B). The effects of the fifth modified example are similar to those of the third and fourth embodiments.

[0050] <Sixth Modification> 6F is a partially enlarged view of the ACR20I of the sixth modified example. The positioning tool 100I constituting the ACR20I of the sixth modified example is a modification of the ACR20A of the second embodiment (see FIG. 3A and FIG. 3B). Specifically, the pressing parts 130A of the ACR20A of the second embodiment are sandwiched between both sides of the measuring tape 14 in pairs. In addition, the curved plate 110 is a two-ply plate with a curved plate connecting the pair of pressing parts 130A. The effect of the sixth modified example is that the positioning tool 100A of the second embodiment is less likely to come off the measuring tape 14. Other effects of the sixth modified example are similar to those of the first and second embodiments.

[0051] <Seventh Modification> 6G is a partially enlarged view of the ACR20J of the seventh modified example. The positioning tool 100J constituting the ACR20J of the seventh modified example is a modification of the ACR20I of the sixth embodiment (see FIG. 6F). Specifically, the protruding parts 120 of the ACR20I of the sixth embodiment are arranged in pairs on both sides of the measurement tape 14. The effects of the seventh modified example are similar to those of the fifth modified example. Moreover, other effects of the seventh modified example are similar to those of the sixth modified example.

[0052] <Eighth Modification> Fig. 6H is a partially enlarged view of the ACR20K of the eighth modified example. The positioning tool 100K constituting the ACR20K of the eighth modified example is a modification of the ACR20J of the seventh embodiment (see Fig. 6G). Specifically, a pair of protruding parts 120 of the ACR20J of the seventh embodiment are overlapped twice in the thickness direction, and each is bent on the outside in the width direction, so that both ends extend beyond both ends of the measuring tape 14 in the width direction and are connected to a pair of pressing parts 130A. The effect of the eighth modification is that, unlike the seventh modification, it can be manufactured by folding a single sheet. Therefore, the positioning tool 100K of the eighth modification can be manufactured more cheaply than the positioning tool 100J of the seventh modification. Other effects of the eighth modification are similar to those of the seventh modification. [Explanation of symbols]
