[0014] The reinforcing tool will be described with reference to Figures 1 to 9. The reinforcing tool 1 is used together with an anchor 2. The anchor 2 will be described with reference to FIG. 9. When attaching an object 10 to an object 11, the anchor 2 is fixed to the object 11. The object is attached to the object 11 via the anchor 2. The object 11 is a wall, beam, and base material of a building. The object 10 to be attached to a building is provided on the outside of the building. Examples of the object 10 include a support member that supports electrical equipment, and a fixing member to which electric wires and communication cables are hooked. Examples of electrical equipment include an antenna and an outdoor unit of an air conditioner. In one example, a support member for an antenna is provided on the wall of a building via the anchor 2.

[0015] The anchor 2 is fixed to the object 11. The anchor 2 has a structure that allows it to be attached from one side of the object 11. The anchor 2 has a shaft portion 21 and a lock portion 22. A male thread portion 23 into which a nut 3 is screwed is provided at a first end 21a of the shaft portion 21. The lock portion 22 is rotatably provided at a second end 21b of the shaft portion 21. A support pin 24 that rotatably supports the lock portion 22 is provided at the second end 21b of the shaft portion 21. The support pin 24 supports a bearing portion 22c that is located from the midpoint of the lock portion 22 toward the first end 22a of the lock portion 22. The lock portion 22 has a first portion 25 from the bearing portion 22c to the first end 22a and a second portion 26 from the bearing portion 22c to the second end 22b. The second portion 26 is longer than the first portion 25. The locking portion 22 is rotated to be placed at least in a parallel state position and an intersecting state position. The parallel state position of the locking portion 22 indicates the position of the locking portion 22 where a line along the longitudinal direction of the locking portion 22 and the axis of the shaft portion 21 are parallel (see the two-dot chain line in FIG. 9). The intersecting state position of the locking portion 22 indicates the position of the locking portion 22 where a line along the longitudinal direction of the locking portion 22 and the axis of the shaft portion 21 intersect (see the solid line in FIG. 9). The anchor 2 is inserted into the through hole 14 of the object 11 with the locking portion 22 placed in the parallel state position. The through hole 14 extends from the front surface 12 to the back surface 13 of the object 11. The shaft portion 21 is inserted into the back side of the object 11, and the shaft portion 21 is rotated about its axis to place the lock portion 22 in the intersecting position, and the shaft portion 21 is pulled back to bring the lock portion 22 into contact with the back surface 13 of the object 11. Thereafter, the nut 3 is fitted onto the male thread portion 23 of the shaft portion 21, and the nut 3 is tightened to fix the anchor 2 to the object 11.

[0016] In such an anchor 2, the locking portion 22 is pressed against the back surface 13 of the target object 11, and force is concentrated near the open end of the through hole 14 of the target object 11. For example, if the nut 3 is tightened too much, the first portion 25 of the locking portion 22 may bite into the target object 11, which may cause cracks in the target object 11. Also, if an object attached to the anchor 2 is swung by a strong wind, the anchor 2 will sway along with the object. At this time, the first portion 25 and the second portion 26 of the locking portion 22 will bite into the target object 11. In this case, the first portion 25 of the locking portion 22 is more likely to bite into the target object 11 than the second portion 26. For this reason, it is preferable to reinforce the portion of the target object 11 with which the first portion 25 of the locking portion 22 comes into contact.

[0017] The reinforcing device 1 will be described with reference to FIG. The reinforcing tool 1 reinforces the object 11 to which the anchor 2 is fixed. Here, the anchor 2 is configured so as to be attached from one side of the object 11. The reinforcing tool 1 includes a guide portion 31 and a reinforcing portion 32. The reinforcing tool 1 further includes a positioning portion 36. Preferably, the reinforcing tool 1 further includes a handle portion 38.

[0018] The guide portion 31 is disposed along the through hole 14 of the object 11 through which the anchor 2 is inserted. The guide portion 31 is elastic. The guide portion 31 has a first end 31a and a second end 31b opposite to the first end 31a.

[0019] The reinforcing portion 32 is provided at a first end portion 31a of the guide portion 31. The reinforcing portion 32 is configured to be placed on the back surface 13 of the target object 11 (see FIG. 9). The back surface 13 of the target object 11 is the surface opposite to the front surface 12 into which the anchor 2 is inserted. Specifically, the reinforcing portion 32 is configured to be insertable into the through hole 14. The size of the reinforcing portion 32 is smaller than the opening area of ​​the through hole 14.

[0020] The width WA of the reinforcing portion 32 is larger than the width WR of the locking portion 22 (see FIG. 7). The width WA of the reinforcing portion 32 is the width in the lateral direction DX of the reinforcing portion 32. The lateral direction DX is a direction intersecting the longitudinal direction DL of the guiding portion 31 and the direction DY in which the reinforcing portion 32 rises from the guiding portion 31. The width WR of the locking portion 22 is the width in the axial direction of the support pin 24.

[0021] The reinforcing portion 32 is provided so as to be perpendicular to the guide portion 31. In the reinforcing portion 32, an edge 32a opposite to the portion connected to the guide portion 31 is configured in a shape of a circular arc or a shape similar to a circular arc. The reinforcing portion 32 has a first surface 32b and a second surface 32c opposite to the first surface 32b. The first surface 32b is a surface facing the handle portion 38 in the longitudinal direction DL (see FIG. 4).

[0022] The reinforcing portion 32 has a protruding portion 33. The protruding portion 33 is configured to come into contact with the object 11 when the reinforcing device 1 is attached to the object 11. Specifically, the protruding portion 33 protrudes from a first surface 32b of the reinforcing portion 32. Preferably, the protruding portion 33 is formed by pressing the reinforcing portion 32. A recess 34 corresponding to the protruding portion 33 is provided on a second surface 32c of the reinforcing portion 32.

[0023] The positioning portion 36 positions the guide portion 31 relative to the through hole 14 of the target object 11. The positioning portion 36 is provided on the guide portion 31 and configured to contact the inner surface of the through hole 14. The positioning portion 36 is provided closer to the handle portion 38 than the midpoint of the guide portion 31. The positioning portion 36 is configured as a ring, a shape similar to a ring, or an arc. In one example, the positioning portion 36 is configured as a ring through which the shaft portion 21 of the anchor 2 can be inserted. The ring may be divided into two parts.

[0024] The handle portion 38 is configured as a portion to be held by an operator. The handle portion 38 is provided at the second end portion 31b of the guide portion 31. The handle portion 38 is configured to be separable from the guide portion 31. Specifically, the connecting portion between the handle portion 38 and the guide portion 31 is configured to be constricted. The gripping surface 38a of the handle portion 38 faces the direction DY in which the reinforcing portion 32 stands up. With this structure, the reinforcing portion 32 can be placed at a desired position with respect to the through-hole 14 of the target object 11 in a state in which the reinforcing portion 32 cannot be seen.

[0025] The deployment member 40 for forming the reinforcement device 1 will be described with reference to Fig. 2. The deployment member 40 is made of metal. The deployment member 40 is made of iron, an iron alloy, an aluminum alloy, or a fiber-reinforced resin.

[0026] The reinforcing device 1 is formed by bending a deployment member 40. The deployment member 40 is cut out from sheet metal. The deployment member 40 has the same shape as the reinforcing device 1 when deployed. The deployment member 40 has a handle portion 38, a guide portion 31, a reinforcing portion 32, and two positioning deployment portions 41. The handle portion 38, the guide portion 31, and the reinforcing portion 32 are connected in this order. The two positioning deployment portions 41 protrude from both side edges so as to be perpendicular to the guide portion 31. The positioning portion 36 is formed by bending the two positioning deployment portions 41 so that the tips of the two positioning deployment portions 41 face each other.

[0027] The procedure for attaching the reinforcement tool 1 and the anchor 2 will be described with reference to FIGS. 3, when attaching an object 10, a through hole 14 is formed in an object 11. The through hole 14 is formed by a drill. The diameter of the through hole 14 is large enough for the shaft 21 of the anchor 2 to pass through and for the positioning portion 36 of the reinforcing tool 1 to fit in.

[0028] Next, the worker holds the handle 38 and inserts the reinforcing part 32 of the reinforcing tool 1 into the through hole 14. At this time, the guide part 31 is curved as shown in Fig. 4. The worker pushes the reinforcing tool 1 to insert the reinforcing part 32 to the back.

[0029] 5, when the reinforcing portion 32 passes through the through hole 14, the curved guide portion 31 returns to its original shape, and the guide portion 31 is disposed so as to follow the through hole 14. In this state, the worker points the guide portion 31 upwards on the upper surface of the handle portion 38. Then, the reinforcing portion 32 is positioned above the open end of the through hole 14.

[0030] Next, the worker places the locking portion 22 in the parallel state position and inserts the anchor 2 into the through hole 14. The worker inserts the anchor 2 deep into the through hole 14 until the locking portion 22 passes through the through hole 14. When the locking portion 22 passes through the through hole 14, the locking portion 22 rotates so that the second portion 26, which is heavier than the first portion 25, is positioned below the first portion 25. In this way, the locking portion 22 is placed in the crossed state position. In this state, the worker pulls the anchor 2. Then, the locking portion 22 comes into contact with the back surface 13 of the object 11.

[0031] 6 and 7, the first portion 25 of the locking portion 22 comes into contact with the reinforcing portion 32 of the reinforcing tool 1. By pulling the anchor 2, the reinforcing portion 32 of the reinforcing tool 1 is pressed against the back surface 13 of the target object 11.

[0032] 8, the worker twists the handle portion 38 to separate the handle portion 38 from the guide portion 31. The handle portion 38 may be separated from the guide portion 31 by using nippers or scissors.

[0033] 9, the washer 4 is fitted onto the shaft 21, the nut 3 is screwed onto the shaft 21, and the nut 3 is tightened via the washer 4. Then, the first part 25 of the locking part 22 presses the reinforcing part 32, and the second part 26 of the locking part 22 presses the back surface 13 of the object 11, and the anchor 2 is fixed by the axial force. The object 10 to be attached to the object 11 is attached to the shaft 21 of the anchor 2 by tightening another nut 3X.

[0034] The operation of this embodiment will now be described. In the anchor 2 that is attached to the object 11 from one side, the first portion 25 of the locking portion 22 may bite into the vicinity of the opening end of the through hole 14 in the object 11 due to tightening of the nut 3, which may cause a crack to occur near the opening end of the through hole 14 in the object 11. In this regard, according to the reinforcing tool 1 of this embodiment, the reinforcing tool 1 is inserted from one side into the through hole 14 provided in the object 11, so that the reinforcing portion 32 can be disposed near the opening end of the through hole 14 in the object 11. This allows the locking portion 22 of the anchor 2 to abut against the reinforcing portion 32, thereby suppressing deformation or deterioration around the through hole 14 in the object 11.

[0035] The effects of this embodiment will be described. (1) The reinforcing tool 1 includes a guide portion 31 and a reinforcing portion 32 provided at an end portion of the guide portion 31. The reinforcing portion 32 is configured to be disposed on the back surface 13 of the target object 11. With this configuration, the portion of the target object 11 that comes into contact with the lock portion 22 of the anchor 2 can be reinforced. This makes it possible to suppress deformation or deterioration of the target object 11.

[0036] (2) The guide portion 31 has elasticity. The reinforcing portion 32 is configured to be insertable into the through hole 14. According to this configuration, when the guide portion 31 is inserted into the through hole 14 and the reinforcing portion 32 is disposed on the back surface 13 of the object 11, the reinforcing portion 32 can be smoothly passed through the through hole 14.

[0037] (3) The reinforcing tool 1 further includes a positioning portion 36. The positioning portion 36 is a portion that positions the guide portion 31 with respect to the through hole 14 of the target object 11. The positioning portion 36 is provided on the guide portion 31, and is configured to contact the inner surface of the through hole 14. With this configuration, the guide portion 31 can be positioned at an appropriate position in the through hole 14 of the target object 11.

[0038] (4) The reinforcing tool 1 further includes a handle portion 38. The guide portion 31 has a first end portion 31a where the reinforcing portion 32 is provided, and a second end portion 31b opposite the first end portion 31a. The handle portion 38 is provided on the second end portion 31b of the guide portion 31. This configuration facilitates the operation of inserting the guide portion 31 and the reinforcing portion 32 into the through hole 14 of the target object 11.

[0039] (5) The handle portion 38 is configured to be separable from the guide portion 31. With this configuration, the nut 3 can be tightened all the way to the back of the shaft portion 21. For example, the connecting portion between the handle portion 38 and the guide portion 31 is configured to be constricted.

[0040] (6) The reinforcing portion 32 is provided so as to be perpendicular to the guide portion 31. According to this configuration, the guide portion 31 is disposed so as to be aligned with the through hole 14 of the object 11, and the reinforcing device 1 can be disposed so that the reinforcing portion 32 is in contact with the back surface 13 of the object 11.

[0041] (7) The reinforcing portion 32 has a protruding portion 33. The protruding portion 33 is configured to come into contact with the target object 11 when the reinforcing device 1 is attached to the target object 11. With this configuration, when the anchor 2 is attached to the target object 11, the protruding portion 33 of the reinforcing portion 32 can be caused to bite into the target object 11. This makes it possible to prevent the reinforcing portion 32 from shifting in position.

[0042] <Modification> The above embodiment is an example of a form that the reinforcing device 1 can take, and is not intended to limit the form. The reinforcing device 1 can take a form different from the form exemplified in the embodiment. One example is a form in which part of the configuration of the embodiment is replaced, changed, or omitted, or a form in which a new configuration is added to the embodiment. An example of a modified embodiment is shown below.

[0043] The form of the anchor 2 used with the reinforcing tool 1 is not limited. The anchor 2 may be one that can be attached to the object 11 from one side. An anchor 2 in which the locking portion 22 is biased by a spring may be used.

[0044] The positioning portion 36 of the reinforcing tool 1 may be omitted. In the case where the positioning portion 36 is omitted, the reinforcing tool 1 is inserted into the through hole 14 of the target object 11, and while holding the reinforcing tool 1, the anchor 2 is inserted into the through hole 14 of the target object 11.
