  Conventional washers can only be used as washers. On the other hand, when the shape of the moving rope mounting bracket of Patent Document 1 is applied to the shape of the washer as it is, the screws that can be used are limited to one type having the same diameter.

  An object of the present invention is to provide a washer that can be applied to a plurality of types of screws having different diameters and that has a convenient function other than the washer.

  The washer of the first device is a washer comprising a plate-shaped member, and includes a first annular portion having a first outer diameter and a first inner diameter, and a second annular portion having a second outer diameter and a second inner diameter. And the first and second annular portions are connected to each other at a part of the outer periphery so that a predetermined inclination angle is formed between the first and second annular portions and a side edge of the connection portion forms a recess. The first and second inner diameters are different from each other, and the first and second annular portions can function as washers for screws having different diameters.

  According to the first device, since the first and second annular portions have different inner diameters, they can be used as washers for two types of screws having different diameters. Further, the annular portion that is not used as a washer can be used as a fixing hole for attaching equipment when a predetermined article such as a tool is tied or hooked. And, when the first and second annular portions are connected at a predetermined angle, the ring portion that is not used as a washer is attached to which the annular portion that is the washer is attached when tying or the like. Since a predetermined gap is formed between the surface and the surface, it is easy to perform operations such as stringing through the gap.

  Furthermore, when the screw is inserted into one annular part and tightened, the entire washer is easily rotated. However, if the recess of the connection part is used as a locking part by a locking tool or a finger, the circular part of the annular part is used. Compared with the case where the edge is locked by the locking tool, the locking tool becomes difficult to slip, and the accompanying rotation can be efficiently prevented. Thereby, the cyclic | annular board part of the direction used for a fixture attachment part can be efficiently match | combined with the exact direction.

  The washer of the second device is the washer of the first device, wherein the connecting portion is a plate-like connecting portion having a predetermined length, and the connecting portion is one of the first and second annular portions on one end side. And having the predetermined inclination angle, and the other end of the first and second annular portions are aligned and connected in the same plane.

  According to the second device, when one annular part is used as a washer, the other annular part has a distance from the mounting surface with which the one annular part is in contact with the one annular part and the connecting part. Since the length of the connecting portion increases by a predetermined angle between them, attachment of a string or the like to the other annular portion not used as a washer becomes efficient.

  The washer of the third device is the washer of the first or second device, wherein the first outer diameter is a value in the range of 7 mm to 18 mm, and the second outer diameter is a value in the range of 4 mm to 10 mm. The first inner diameter is a value in the range of 3.2 mm to 8.5 mm, and the second inner diameter is a value in the range of 2 mm to 5 mm.

  According to the third device, a washer having a size as large as a fingertip is used as a screw that attaches only the washer to a predetermined member, not a screw that is inserted through the washer. It can be used for hooking. In that case, the washer can correspond to a plurality of types of screws having different diameters.

  The washer of the fourth device is the washer of any one of the first to third devices, wherein the predetermined inclination angle is a value within a range of 30 ° to 45 °.

  According to the fourth device, it is possible to form a gap having an appropriate dimension between the annular portion that is not used as a washer so as not to become an obtrusive protrusion and a member to which the washer is attached.

  1A, 1B, and 1C are a front view, a right side view, and a perspective view, respectively, of a washer 10, and the washer 10 includes a large-diameter washer portion 11 that is connected to each other at one location on the outer periphery. The small-diameter washer portion 12 is provided, and is manufactured from an integral plate member by punching or the like. Each of the large-diameter washer portion 11 and the small-diameter washer portion 12 has annular portions 13 and 15 having through-holes 14 and 16 at the centers, respectively.

  The washer 10 has a plane-symmetric structure in which a plane that passes through the centers of the circular through holes 14 and 16 and is perpendicular to both the large-diameter washer portion 11 and the small-diameter washer portion 12 is a plane of symmetry. When the direction perpendicular to the plane of symmetry is defined as the width direction of the washer 10, the width of the washer 10 is minimal at the connecting portion of the large-diameter washer portion 11 and the small-diameter washer portion 12, and the width direction at the connecting portion is the width direction. The edges on both sides form a recess 17.

  The large-diameter washer portion 11 and the small-diameter washer portion 12 have a structure that functions as a washer individually, and the through holes 14 and 16 of the large-diameter washer portion 11 and the small-diameter washer portion 12 are selected to have different diameters. Therefore, the washer 10 is a washer corresponding to a screw having two types of large and small diameters.

In FIG. 1A, each symbol represents the following specifications.
d: inner diameter of large-diameter washer portion 11: outer diameter of large-diameter washer portion 11 v: inner diameter of small-diameter washer portion 12 B: outer diameter of small-diameter washer portion 12 θ in FIG. The angle of the protruding direction of the small-diameter washer portion 12 with respect to the extending direction of the large-diameter washer portion 11 is shown as a connection angle, and is a value within a range of 30 ° to 45 °, for example.

  In FIG. 2, the washer 10 is tentatively named tw, for example, and those having different values are identified by tentative names of 3, 4, 5, 6, and 8. tw3 has the smallest diameter in tw, and tw8 has the largest diameter. The values of each item in FIG. 2 are as shown, and the unit is mm.

  In FIG. 3, in the washer 10, the large-diameter washer portion 11 is used for the original function of the washer, and the small-diameter washer portion 12 is used as a fixture attachment portion. Depending on the diameter of the bolt 21, the small-diameter washer portion 12 can be used for the original function of the washer, and the large-diameter washer portion 11 can be used as a fixture mounting portion.

  In FIG. 3, the bolt 21 is inserted through the through hole 14 of the large-diameter washer portion 11. The bolt 21 has its tip applied to the screw hole of the housing 20 and is then tightened and screwed into the screw hole to fasten the annular portion 13 of the large-diameter washer portion 11 to the mounting surface.

  When the bolt 21 is tightened, the washer 10 easily rotates with the bolt 21, and the small-diameter washer portion 12 to be used as the fixture mounting portion is in an inappropriate direction. Therefore, the operator applies the tip or finger of the locking tool to one or both of the recesses 17 to lock the washer 10 and tighten the bolt 21 while preventing the washer 10 from rotating. Thereby, the operator can efficiently set the small diameter washer portion 12 in an appropriate direction.

  The housing 20 is, for example, a factory machine or equipment, furniture in the home, rack, electrical appliance, or the like, a member in the vehicle, an outdoor artificial article, or a wall of a building. As the screw hole on the side of the housing 20 to which the bolt 21 is screwed, a screw hole originally present in the housing 20 is typically used. The bolt 21 is essentially a fastening tool that fastens a predetermined member (not shown) to a predetermined position of the housing 20, and the washer 10 is a conventional washer for the fastening tool (having one through hole). The small-diameter washer portion 12 that is used in place of a single washer and is not used as a washer is used as a fixture mounting portion such as stringing described below. Note that the bolt 21 can also be used exclusively for attaching the washer 10 only to the housing 20.

  The wire 24 includes a wire portion 25 extending at a predetermined length in the middle, and loops 26 and 27 provided at both ends of the wire portion 25. The wire 24 is passed through the through hole 16 of the small-diameter washer portion 12 in the loop 26, and the washer 10. It is locked to. In FIG. 3, the loop 26 is illustrated as a loop, but before passing through the through hole 16, the loop 26 is a wire with an end. The end of the wire is passed through the annular portion 15, and then folded. The end is fixed to the base portion of the wire with a fastening member, a fixing member, or a fixing band to prevent the end of the wire, thereby forming a loop.

  On the other hand, the tool 28 is passed through the loop 27 of the wire 24 in the hole of the base portion, and the wire 24 is tied. Typically, the tool 28 is suspended from the housing 20 via the wire 24. Thus, as a result of the tool 28 being tied to the housing 20 via the wire 24, the tool 28 is prevented from being lost, or the operator or the operator forgets the place where the tool 28 is placed, and the tool 28 is used at the next use of the tool 28. The situation where 28 is not found can be prevented.

  In the example of FIG. 3, since the tool 28 is kept tied to the housing 20 by the wire 24 even during use, the working range of the tool 28 is limited to the range of the length of the wire 24 from the housing 20. Is done. However, when at least one of the loops 26 and 27 is a hook, and the tool 28 is in use, the hook 28 is removed to release the connection of the tool 28 to the housing 20 so that the work is sufficiently separated from the housing 20. It is also possible to take the tool 28 at a location.

  In FIG. 3, the shaft portion of the bolt 21 is inserted into the through hole 14 of the large-diameter washer portion 11, and the large-diameter washer portion 11 is used as a washer and the small-diameter washer portion 12 is used as a fixture mounting portion. On the other hand, for a bolt having a shaft having a diameter different from that of the bolt 21, the bolt is passed through the through hole 16 of the small-diameter washer portion 12 to fix the small-diameter washer portion 12 to the housing 20. The washer portion 12 is used as a washer, and the large-diameter washer portion 11 is used as a fixture tying portion.

  FIG. 4A is an explanatory view showing a state in which the tension spring 31 is locked to the washer 10. 4A, the tension spring 31 has an intermediate coil portion 32 and hooks 33 at both ends (only the end on the washer 10 side is shown). The hook 33 is hooked on the through hole 16 and locked. . A hook 33 (not shown) on the opposite side of the washer 10 of the tension spring 31 is hooked in a locking hole of the tool 28 (FIG. 2), and when the tool 28 is not used, the coil portion 32 has a spring contracting force. Thus, the length is reduced so that the entire tension spring 31 becomes compact. On the other hand, when the tool 28 is used, since the operator pulls the tool 28, the coil portion 32 increases in length by a tensile force from the operator, and as a result, the operator links the tool 28 to the housing 20. The tool 28 can be moved to a work location sufficiently away from the housing 20.

  FIG. 4B is an explanatory view showing a state where the strip 35 is bound to the washer 10. In FIG. 4B, the strip 35 as a whole constitutes one loop, forms a U-turn portion at one position of the loop, passes the tip of the U-turn portion through the hole 16, and then the U-turn portion. The U-turn portion is contracted and joined to the small-diameter washer portion 12 by expanding the turn portion and pulling out the other portion of the strip 35 into the U-turn portion.

  Next, a washer 40 according to another embodiment will be described. 5A and 5B are a front view and a right side view of the washer 40, respectively. The structural difference between the washer 40 and the washer 10 in FIG. 1 is that the washer 40 has a connecting plate portion 47 between the large-diameter washer portion 41 and the small-diameter washer portion 42.

  The washer 40 includes a large-diameter washer portion 41 and a small-diameter washer portion 42 that are connected to each other at one location on the outer peripheral portion, and a connecting plate portion 47 that connects them to each other. Produced. The large-diameter washer portion 41 and the small-diameter washer portion 42 have annular portions 43 and 45 having through holes 44 and 46, respectively, in the center.

  The specifications of the large diameter washer portion 41 and the small diameter washer portion 42 are the same as those of the large diameter washer portion 11 and the small diameter washer portion 12 of the washer 10. Further, both the large-diameter washer portion 41 and the small-diameter washer portion 42 of the washer 40 function as a washer, and the washer 40 can correspond to a washer for two types of screws having different diameters, as in the case of the washer 10.

  When the width direction of the washer 40 is a direction perpendicular to the plane of symmetry of the washer 40 in the same manner as the width direction in the case of the washer 10, the washer 40 has a large-diameter washer portion 41 on both sides in the vertical direction in the connecting plate portion 47 and The width is reduced with respect to the small-diameter washer portion 42, and a depression is formed like the depression 17 of the washer 10. Therefore, the operator can use the connecting plate portion 47 as a locking portion for preventing the washer 40 from being rotated when the bolt 21 is tightened, as in the case of the recess 17 of the washer 10. .

  The connecting plate portion 47 is aligned with the small-diameter washer portion 42 in the same plane, but is connected to the large-diameter washer portion 41 at an angle θ (FIG. 5B). The θ is a value within a range of 30 ° to 45 ° as in the case of the washer 10 (FIG. 1B).

  Due to the presence of the connecting plate portion 47, the small diameter washer portion 42 can be farther away from the mounting surface of the housing 20 than the small diameter washer portion 12 of the washer 10. As a result, it is easy to pass the string through the through hole 46 of the small diameter washer portion 42 or to hook the hook.

  In the washer 40 of FIG. 5, the small diameter washer portion 42 and the connecting plate portion 47 are aligned so that they are flush with each other, but a predetermined angle is also formed between the small diameter washer portion 42 and the connecting plate portion 47. In addition, the orientation of the surface of the small diameter washer portion 42 (the direction of the normal to the surface of the small diameter washer portion 42) can be changed. In that case, the plate surface of the small-diameter washer portion 42 can be made parallel to the plate surface of the large-diameter washer portion 41.

  In the washers 10 and 40, only two annular portions are provided, but three or more annular portions can be provided. In that case, it is possible to arrange other annular parts at equal angular intervals in the circumferential direction around one annular part, arrange only on one half circumference side, or arrange three or more annular parts in series. it can.

  In addition to the tool 28, what is tied to the housing 20 may be a so-called FA product such as a slide guide in addition to a writing instrument, a manual, a seal, a key, a remote controller, or the like.
