[0004] However, in the case of the above-mentioned staffs, they are long materials made of, for example, wood or aluminum, and therefore are difficult to carry and store. Also, while it is possible to use a so-called convex staff consisting of a case and a measuring tape, in the case of a convex staff, the presence of the case tends to make the staff heavy and large, making them difficult to carry and store. In addition, the heavy and large staffs can place a heavy burden on the worker when working at heights, and can pose a risk to the worker, which can be a variety of inconveniences. [Means for solving the problem]

The suspending member is formed by a cover portion that covers the front side of the winding portion of the tape measure tape, a pair of opposing guide portions that can guide both side edge portions of the tape measure tape, and a suspending portion that is inserted into a core hole portion of the winding portion and can suspend the winding portion, the suspending member is pivotally connected to the terminal side slider by a connecting shaft, and the suspending member is disposed so as to be swingable between the back side direction of the tape measure tape and the front side direction of the tape measure tape about the axis of the connecting shaft, and a positioning mechanism is provided that can position the suspending member at a guide position on the back side of the tape measure tape and a retracted position on the front side of the tape measure tape, respectively. The tape measure is characterized by the following.

[Effects of the Invention]

[0010] As described above, in the invention of claim 1, when the terminal slider is slid toward the terminal side, the wound portion of the terminal side of the tape measure is unwound due to the inherent straightness retention as it slides toward the terminal side, and the tape measure is held in a straight line. Also, when the terminal side of the tape measure is folded over to the back side of the tape measure, the tape measure is wound in a flat cross section due to the inherent winding retention that is dependent on the arc cross section of the tape measure. Furthermore, when the terminal slider is slid toward the start side, the terminal side of the tape measure is unwound due to the inherent straightness retention that is dependent on the arc cross section of the tape measure. Due to the inherent winding and holding ability, the tape is wound into a flat cross-sectional shape, forming a wound portion on the back side of the tape; therefore, as the end slider slides toward the start side, the tape is wound at the end side of the tape by the inherent winding and holding ability, forming a wound portion on the back side of the tape; and as the end slider slides toward the end side, the inherent straightness holding ability unwinds the wound portion on the end side of the tape and holds it in a straight line; at this time, the tape is composed of the tape, the start side slider, the end side slider, and the hanging member, which allows for lighter weight and smaller size. The tape measure can be made lighter and smaller than a so-called convex tape measure consisting of a case and tape measure, and the lighter and smaller size improve portability and storability, reduce the burden on workers when working at heights, avoid danger to workers, and increase work safety. Furthermore, when used for photography, etc., the end slider is slid toward the end side, and as it slides toward the end side, the tape measure tape's inherent linearity, which is dependent on the arc-shaped cross section, allows the tape measure tape to retract at the end side of the tape measure. When unwound, the tape measure can be held in a straight line, and when not in use, such as when carried, the terminal slider is slid toward the starting end, and as the terminal slider slides toward the starting end, the tape measure is wound into a flat cross-sectional shape at the terminal end due to the inherent winding and holding ability that is dependent on the arc cross-sectional shape of the tape measure, forming a wound portion on the back side of the tape measure, and the sliding of the terminal slider allows the tape to be instantly adapted to be in use or not in use, and further, the terminal slider is provided with a hanging member that can hang the wound portion of the tape measure,This prevents the self-unwinding phenomenon, or so-called sagging phenomenon, that occurs due to the weight of the wound part of the tape measure, and allows the tape measure to be carried safely.In this case, since both the start-side slider and the end-side slider are provided so as to be freely attached and detached to the tape measure tape, the tape measure tape can be detached from the start-side slider and the end-side slider, and the tape measure tape can be held in a straight line due to its inherent straightness-retaining ability that relies on the cross-sectional arc shape.This means that the tape can be used, for example, as a staff for measuring height dimensions in leveling surveys, and this reduces the burden on workers when working at heights, avoids danger to workers, and increases work safety. Furthermore, the suspending member is formed of a cover portion that covers the front side of the winding portion of the tape measure, a pair of opposing guide portions that can guide both side edge portions of the tape measure, and a suspending portion that is inserted into the core hole of the winding portion and can suspend the winding portion, so the cover portion and guide portions of the suspending member can protect the front side and both side edge portions of the winding portion from external forces, and further, the suspending member is pivotally connected to the terminal side slider by a connecting shaft, and the suspending member is disposed so as to be able to swing freely between the back side direction of the tape measure and the front side direction of the tape measure around the axis of the connecting shaft, so the suspending member can swing in accordance with the winding diameter of the winding portion as the tape measure is wound and unwound, and the tape measure can be wound and unwound smoothly, and for example, it is possible to measure the spacing between reinforcing bars, inspect them, and take photographs of the reinforcement arrangement state. The tape measure can be wound and unwound smoothly. The positioning mechanism allows the suspension member to swing at the guide position on the back side of the tape measure and at the retracted position on the front side of the tape measure, so that the suspension member can swing at the guide position according to the diameter of the wound portion as the tape measure is wound and unwound at the guide position, allowing the tape measure to be wound and unwound smoothly. The positioning mechanism allows the suspension member to be positioned and fixed at the guide position and the retracted position, and when the terminal side slider is slid toward the terminal side of the tape measure and there is no wound portion, the suspension member can be swung from the guide position to the retracted position, so that the bottom surface of the terminal side slider can be brought into close contact with the object to be measured. For example, it can be brought into close contact with multiple rebars, allowing accurate measurement of the spacing between rebars, inspection, and photographing of the reinforcement state.

[0011] In the invention of claim 2, a movable claw member is arranged at the starting end of the tape measure, having a pressing surface that is pressed against the measurement surface of the object to be measured and a hooking surface that is hooked onto the measurement surface of the object to be measured.Therefore, pressing measurement can be performed by pressing the pressing surface against the measurement surface of the object to be measured, or hooking measurement can be performed by hooking the hooking surface onto the measurement surface of the object to be measured.The movable claw member moves in accordance with pressing measurement and hooking measurement, and measurement can be easily performed by moving the movable claw member.In addition, in the invention of claim 3, a permanent magnet is arranged on the movable claw member, and the movable claw member can be fixed to the object to be measured by the magnetic attraction of the permanent magnet, making pressing measurement easy.

[0012] Furthermore, in the invention described in claim 4, a tilting member that can be raised and lowered and that can press the surface of the tape measure tape against the end side slider is provided on the end side slider, and a tilting operation mechanism is provided that can press and fix the surface of the tape measure tape and release it by raising or lowering the tilting member.Therefore, the tilting operation mechanism can be used to lower the tilting member, thereby pressing and fixing the surface of the tape measure tape, preventing the tape measure tape from sliding toward the end side and the start side, preventing unexpected sliding of the tape measure tape, and making measurements easy.

[0013] Also, claims 5In the invention described above, a retaining pin is disposed at the end of the tape, and a retaining portion that can strike the retaining pin is formed on the end slider, so that the tape can be prevented from coming off the end slider. This, combined with the retaining action of the start slider by the moving claw member, can prevent the tape from coming off the start slider and the end slider. 6 In the invention described above, since permanent magnets are provided on the start-end slider and the end-end slider, respectively, the start-end slider and the end-end slider can be fixed to the object to be measured, such as a reinforcing bar, by the magnetic attraction of the permanent magnets, and measurements of the intervals between the reinforcing bars, inspections, and photographs of the reinforcing bar arrangement can be easily and accurately performed. 7 In the described invention, permanent magnets are arranged on the top and bottom surfaces of the starting side slider, permanent magnets are arranged on the top and bottom surfaces of the terminal side slider, and length scales are formed on the front and back surfaces of the tape. Therefore, the tape can be fixed to the object to be measured, such as rebar, by the magnetic attraction of the permanent magnets on the top surface of the starting side slider and the top surface of the terminal side slider, or the bottom surface of the starting side slider and the bottom surface of the terminal side slider, and the length scales on the front or back surface of the tape can be visually confirmed. Thus, the tape can be fixed to the object to be measured, such as rebar, by the permanent magnets on both the top and bottom surfaces of the starting side slider and the terminal side slider, and the top and bottom surfaces of the terminal side slider, making it easy and accurate to measure the spacing between rebars, inspect them, and photograph the reinforcement state.

[0014] Also, claims 8 In the invention described above, finger hooks are formed on the start-end slider and the end-end slider, respectively, and a hanging hole is formed in the hanging member. This allows the start-end slider and the end-end slider to be easily slid by the finger hooks, and a hanging member such as a carabiner can be fastened to the hanging hole. The tape measure can be hung from a waist belt or the like worn by the worker by the hanging member, thereby improving workability and portability. 9In the described invention, a plurality of the above-mentioned starting end sliders are prepared, and the plurality of starting end sliders are arranged on the above-mentioned tape measure tape so that they can be attached and detached freely. Therefore, the tape measure can be securely fixed in position on the object to be measured using the plurality of starting end sliders. For example, the tape measure can be securely fixed in position on a plurality of reinforcing bars arranged vertically and horizontally, and measurement of the spacing between the reinforcing bars, inspection, and photographing of the reinforcing bar arrangement can be easily and accurately performed.

[0016] Figures 1 to 17 show an embodiment of the present invention, in which 1 is a tape measure, which in this case is made of metal and has a tape width of 30 mm and a tape length of 210 cm. As shown in Figures 1 and 4, the tape is formed into a cross-sectional arc shape with a concave surface 1a and a convex back surface 1b, and is continuously molded, for example, by roll molding. A length scale M for measuring the length dimension between two points on the object to be measured G is formed on the surface 1a, and the tape measure 1 is endowed with inherent straightness and roll-up properties due to the cross-sectional arc shape.

[0017] Reference numeral 2 denotes the start side slider and 3 denotes the end side slider, both of which are made of synthetic resin. As shown in Figures 4 and 5, arc-shaped insertion holes 2H and 3H are formed in the start side slider 2 and the end side slider 3, respectively. The bottom surfaces 2QS and 3QS of the start side slider 2 and the end side slider 3 are formed as contact surfaces for the object to be measured G. The tape measure 1 is inserted into the insertion holes 2H and 3H, and the above-mentioned cross-sectional arc shape of the tape measure tape 1 is maintained by insertion into the insertion holes 2H and 3H, allowing the tape measure tape 1 to slide linearly between the start side S and the end side E.

[0018] As shown in Figure 2, as the terminal side slider 3 slides toward the starting side S, the tape measure tape 1 is wound up at the terminal side E due to the inherent winding and holding ability, forming a wound portion I on the back surface 1b of the tape measure tape 1; conversely, as the terminal side slider 3 slides toward the terminal side E, the wound portion I on the terminal side E of the tape measure tape 1 is unwound due to the inherent straightness holding ability, and the cross-sectional arc shape is maintained and held in a straight line.

[0019] Reference numeral 4 denotes a hanging member, which in this case is made of synthetic resin and is arranged on the terminal slider 3 as shown in Figures 1 and 6, and is formed so as to be able to hang the winding portion I of the tape measure tape 1, and the tape measure tape 1, the starting slider 2, the terminal slider 3 and the hanging member 4 form the tape measure SK.

[0020] 4 and 5, the start-side slider 2 and the end-side slider 3 are both provided so as to be freely attachable to and detachable from the tape measure 1, and as for the start-side slider 2, as shown in FIGS. 2, 4, 5 and 7, the start-side slider 2 is made up of two members, a lower frame 2a and an upper frame 2b, which can be fitted together with each other, and an insertion hole 2H is formed by forming opposing gaps between two wall portions 2aK·2aK of the lower frame 2a and two wall portions 2bK·2bK of the upper frame 2b, and two side portions 2bS·2bS are formed in the upper frame 2b, and an insertion hole 2H is engaged with the two side portions 2bS·2bS. Slots 2bM·2bM are formed, two side portions 2aS·2aS are formed on the lower frame 2a, locking ridges 2aD·2aD that can be fitted into and removed from the locking slots 2bM·2bM are formed on the two side portions 2aS·2aS, and an insertion groove portion 2aC into which a prying member C such as a coin can be inserted is formed on the bottom of the lower frame 2a, and the prying member C is inserted into the insertion groove portion 2aC to pry open one side portion 2bS of the upper frame 2b, and the lower frame 2a and upper frame 2b of the starting end slider 2 can be disassembled and attached to and detached from each other, so that the starting end slider 2 can be freely attached and detached to and from the tape measure tape 1.

[0021] 4 and 5, the terminal slider 3 is made up of two members, a lower frame 3a and an upper frame 3b, which can be fitted together. Opposing gaps are formed between three wall portions 3aK·3aK·3aK of the lower frame 3a and two wall portions 3bK·3bK of the upper frame 3b, forming insertion holes 3H. Two side portions 3bS·3bS are formed in the upper frame 3b, and a locking slot 3bM is formed in one of the side portions 3bS. Two side portions 3aS·3aS are formed in the lower frame 3a, and a locking slot 3bM is formed in one of the side portions 3bS. One side 3bS of the upper frame 3b is pivotally attached to the side 3aS by a pivot 3bJ so that it can be opened and closed freely, and the other side 3aS is formed with a locking ridge 3aD that can be fitted into and removed from the locking groove 3bM. Thus, one side 3bS of the upper frame 3b can be opened and closed freely around the axis O1 of the pivot 3bJ, and the locking groove 3bM and the locking ridge 3aD can be fitted and removed freely, and the lower frame 3a and the upper frame 3b can be opened and closed and attached and detached from each other, so that the terminal side slider 3 can be attached and detached freely to and from the tape measure tape 1.

[0022] 4 and 5, a fitting hole 3bH is formed in the upper frame 3b of the terminal side slider 3, a pair of opposing bearing slots 3bG and 3bG are formed in the fitting hole 3bH, pivots 5J and 5J that can be pivotally attached to the bearing slots 3bG and 3bG are formed in the terminal side slider 3, and as shown in FIGS. 4, 5, 8 and 9, the terminal side slider 3 is provided with stoppers 3cS and 3cS for the terminal side slider 3, and stoppers 3cS and 3cS for the terminal side slider 3 are formed in the terminal side slider 3, as shown in FIG. As shown in Figures 8 to 9, the tilting member 5 is tilted by the tilting operation mechanism T, and at this time, the distance and positional relationship between the axis O2 of the pivots 5J·5J, which serve as the center of rotation of the tilting member 5, and the point of contact of the tape measure 1 with the tilting member 5 is taken into consideration, so that the surface 1a of the tape measure 1 is pressed against the wall portion 3aK at the center of the lower frame 3a, and the back surface 1b of the tape measure 1 is pressed and fixed against the wall portion 3aK at the center of the lower frame 3a. Also, as shown in Figures 9 to 8, the tilting member 5 is raised by the tilting operation mechanism T, and the pressure on the surface 1a of the tape measure 1 can be released.

[0023] In this case, as shown in Figures 2, 4, 5 and 6, the hanging member 4 is pivotally connected to the terminal side slider 3 by a connecting shaft 3J, and the hanging member 4 is arranged so that it can swing freely between the back surface 1b side of the tape measure tape 1 and the front surface 1a side of the tape measure tape 1, centered on the axis O of the connecting shaft 3J.In this case, as shown in Figure 2, the hanging member 4 is configured with a positioning mechanism D that can position it at a position where it protrudes toward the back surface 1b of the tape measure tape 1 from a plane F including the bottom surface 3QS of the terminal side slider 3, which serves as a guide position GP on the back surface 1b side of the tape measure tape 1, and at a position where it protrudes toward the front surface 1a of the tape measure tape 1 from a plane F including the bottom surface 3QS of the terminal side slider 3, which serves as a retracted position EP on the front surface 1a side of the tape measure tape 1.

[0024] In this case, as shown in Figures 4, 5 and 6, the hanging member 4 is formed by a cover portion 4a that covers the surface side of the winding portion I of the tape measure tape 1, a pair of opposing guide portions 4b / 4b that can guide both side edge portions 1c / 1c of the tape measure tape 1, and a hanging portion 4c that is inserted into the core hole portion IH of the winding portion I and can hang the winding portion I.

[0025] In this case, as shown in Figures 4, 5 and 6, the positioning mechanism D is configured such that support pieces 3d are formed on both sides of the terminal end side E of the terminal end slider 3, positioning protrusions 3e are formed on the outer surfaces of the support pieces 3d, and two positioning holes 4f are formed in the guide sections 4b of the suspension member 4 to selectively fit into the positioning protrusions 3e, so that the suspension member 4 is swung between the guide position GP and the retracted position EP around the axis O of the connecting shaft 3J, and at the guide position GP and the retracted position EP, the positioning protrusions 3e are fitted into either of the positioning holes 4f.

[0026] In this case, as shown in Figures 10 and 12, a movable claw member 6 is disposed on the starting end S of the tape measure 1, and has a pressing surface 6a that presses against the measurement surface G1 of the object G to be measured and a hooking surface 6b that hooks onto the measurement surface G2 of the object G. The movable claw member 6 is formed with upper claw portions 6f·6f that protrude toward the front surface 1a of the tape measure 1 and lower claw portions 6g that protrude toward the back surface 1b of the tape measure 1 of the movable claw member 6. When the top surfaces 2QU·3QU of the starting end slider 2 and the terminal end slider 3 or the bottom surfaces 2QS·3QS of the starting end slider 2 and the terminal end slider 3 are fixed to the object G by a permanent magnet MG, the upper claw portions 6f·6f and the lower claw portions 6g perform hooking measurement on the measurement surface G2 of the object G, and as shown in Figures 5 and 10, 11, 12 and 13, the movable claw member 6 is formed in a hook shape, and is movable relative to the tape measure 1 by the difference in measurement base points between the pressing surface 6a and the hooking surface 6b using the zero point correction mechanism Z. In this case, a presser plate 6c is fixed to the tape measure 1 with four rivets 6d·6d·6d·6d, and three rivets 6d·6d·6d are fixed to the tape measure 1 and the presser plate 6c, and the three rivets 6d·6d·6d are slidably fitted into three elongated holes 6e·6e·6e formed in the movable claw member 6. A permanent magnet MG is disposed on the starting side of the movable claw member 6 so as to protrude from the starting side of the movable claw member 6, and the permanent magnet MG is disposed on the same plane as the rear side of the movable claw member 6. Therefore, the pressing surface 6a is the starting side of the permanent magnet MG. It should be noted that the movable claw member 6 may also have a structure that does not include the permanent magnet MG. In this case, the pressing surface 6a is the side surface at the start end of the movable claw member 6.

[0027] In this case, as shown in Figures 5 and 6, a retaining pin NP is arranged on the terminal side E of the tape measure tape 1, and a retaining portion 3bT that can be struck by the retaining pin NP is formed on the terminal side slider 3, so that the tape measure tape 1 is prevented from slipping out toward the starting end side S by the impact between the retaining pin NP on the terminal side E of the tape measure tape 1 and the retaining portion 3bT of the terminal side slider 3.

[0028] In this case, as shown in Figure 1, permanent magnets MG·· are arranged on the starting side slider 2 and the terminal side slider 3, respectively, and further, in this case, as shown in Figures 4, 6 and 7, permanent magnets MG are arranged on the top surface 2QU and bottom surface 2QS of the starting side slider 2, and permanent magnets MG are arranged on the top surface 3QU and bottom surface 3QS of the terminal side slider 3, and length scales M are formed on the front surface 1a and back surface 1b of the tape measure tape 1, and further, in this case, as shown in Figures 4 and 14, vertical scales MT for measuring the vertical length dimension (height dimension) are formed on the front surface 1a of the tape measure tape 1, and horizontal scales MY for measuring the horizontal length dimension are formed on the back surface 1b of the tape measure tape 1.

[0029] In this case, as shown in Figures 1 and 3, finger hooks 2Y and 3Y are formed on the start-end slider 2 and the end-end slider 3, respectively, and a hanging hole 4e is formed in the protruding piece 4d of the hanging member 4.

[0030] In this case, as shown in Figures 16 and 17, a plurality of the starting end sliders 2 are prepared, and the plurality of starting end sliders 2 are arranged on the measuring tape 1 so as to be freely attachable and detachable.

[0031] Since this embodiment has the above-mentioned configuration, when the end side slider 3 is slid from the state of FIGS. 1 and 2 to the state of FIG. 4 toward the end side E, the winding part I of the end side E of the tape measure tape 1 is unwound due to the inherent straightness retention as it slides toward the end side E, and the tape measure tape 1 is held in a straight line. Also, in the state of FIG. 4, when the end side E of the tape measure tape 1 is folded toward the back surface 1b of the tape measure tape 1, the tape measure tape 1 is wound in a flat cross section due to the inherent winding retention that depends on the cross-sectional arc shape of the tape measure tape 1. Furthermore, when the end side slider 3 is slid toward the start side S, the end side slider 3 is unwound due to the inherent straightness retention that depends on the cross-sectional arc shape of the tape measure tape 1. As the slider 3 slides toward the starting end S, as shown in Figures 1 and 2, the tape measure tape 1 is wound into a flat cross-sectional shape at the end E due to its inherent winding and holding ability, forming a wound portion I on the back surface 1b of the tape measure tape 1.Therefore, as the end side slider 3 slides toward the starting end S, the tape measure tape 1 is wound into a flat cross-sectional shape at the end E due to its inherent winding and holding ability, forming a wound portion I on the back surface 1b of the tape measure tape 1.As the end side slider 3 slides toward the end side E, the wound portion I on the end side E of the tape measure tape 1 is unwound and held in a straight line due to its inherent straightness holding ability.

[0032] In this case, as shown in FIG. 1, the tape measure SK is composed of a tape measure 1, a start side slider 2, a finish side slider 3, and a hanging member 4, so that it can be made lighter and smaller, and can be made lighter and smaller than a so-called convex tape measure consisting of a case and a tape measure. The lighter and smaller size improves portability and storability, reduces the burden on workers when working at heights, avoids danger to workers, and increases work safety. Furthermore, when using the tape for photography or the like, the end side slider 3 is slid toward the end side E, and as the tape is slid toward the end side E, the tape is unwound at the end side E of the tape 1 due to the inherent straightness retention ability that is dependent on the arcuate cross-sectional shape of the tape 1, and the tape 1 can be held in a straight line. When not in use, such as when carried, the end side slider 3 is slid toward the start side S, and as the end side slider 3 is slid toward the start side S, the tape is unwound at the end side E of the tape 1, and the tape 1 can be held in a straight line. 16 and 17, the tape measure tape 1 can be wound into a flat cross-sectional shape, forming a wound portion I on the back surface 1b of the tape measure tape 1, and the sliding of the end side slider 3 can instantly change the state of use or non-use. This significantly improves the workability of measuring and inspecting the spacing P between the reinforcing bars RB·· and taking photographs of the reinforcing bar arrangement, for example.
