The fifth washer 54 e has a ring plate shape and is disposed between the regulating member 6 and the nut 52 so as to contact the regulating member 6 and the nut 52.

  Next, the restriction member 6 will be described. As shown in FIG. 5, the restricting member 6 is formed of a plate-like body in this embodiment, and the handrail holding member applies a force in a direction in which the handrail holding member 3 approaches the concave surface member 4 via the coupling bolt 51. 3, a regulation main body guide portion 62 for guiding the regulation main body portion 61 to a predetermined position where the force in the approaching direction can be applied, and a columnar portion 514 b of the shaft portion 512 of the coupling bolt 51 are inserted. A long hole-like shaft insertion hole 63 (insertion portion) extending in the vertical direction and a pressed portion 64 pressed by the regulating member pressing portion 223 of the second bracket portion 22 are provided.

  The restriction main body 61 is formed on both sides in the width direction of the shaft insertion hole 63 and on one side in the longitudinal direction of the shaft insertion hole 63 with the shaft insertion hole 63 interposed therebetween.

  The restriction main body guide portion 62 is formed on both sides in the width direction of the shaft insertion hole 63 with the shaft insertion hole 63 interposed therebetween so that the thickness gradually decreases from the restriction main body portion 61. In this embodiment, the regulation main body guide portion 62 is configured by forming an inclined surface whose thickness gradually decreases from the regulation main body portion 61 on one surface on the nut 52 side of the regulation member 6. Note that the restriction main body guide portion 62 is not limited to this form, and can be changed as appropriate. For example, an inclined surface whose thickness gradually decreases from the restriction main body portion 61 on the other surface of the restriction member 6 opposite to the nut 52 side. Alternatively, it may be configured such that inclined surfaces whose thickness gradually decreases from the regulation main body 61 are formed on both the one surface and the other surface of the regulation member 6.

  The pressed portion 64 is formed on the upper end surface of the restriction member 6, that is, the end surface of the restriction main body portion 61 opposite to the restriction main body guide portion 62.

  The restricting member 6 configured in this manner is disposed between the fourth washer 54d and the fifth washer 54e with the shaft portion 512 of the coupling bolt 51 inserted through the shaft insertion hole 63.

  The nut 52 is completely tightened up to the root portion of the male screw portion 513. In this tightened state, for example, as shown in FIGS. 8 and 9, if the restricting member 6 is disposed so that the restricting main body guide portion 62 contacts the fourth washer 54d and the fifth washer 54e, the elastic member 53 Although the handrail holding member 3 is pressed against the concave surface member 4 by the elastic force of the handrail and the sliding resistance is applied to the handrail holding member 3, an external force is applied to the handrail holding member 3 by hand against the elastic force of the elastic member 53. If given, the handrail holding member 3 can be slid with respect to the concave member 4. That is, the handrail holding member 3 is temporarily fixed. Then, when the restriction member 6 is moved from the state shown in FIGS. 8 and 9 to the position shown in FIGS. 4 and 6 where the restriction main body 61 enters between the fourth washer 54d and the fifth washer 54e, the coupling bolt 51, the handrail holding member 3 is pulled into the concave member 4 side, and the handrail holding member 3 is strongly pressed against the concave member 4 via the second washer 54b. As a result, the handrail holding member 3 cannot slide. It becomes. That is, the handrail holding member 3 is in a fixed state.

  Next, the effect of the handrail bracket 1 will be described together with the method of using the handrail bracket 1. First, for example, the wall surface attaching portion 7 is attached to a predetermined position of the wall surface 120 by a positioning bolt and an attaching bolt (not shown). And the 1st bracket part 21 of the bracket main body 2 is assembled | attached to the wall surface attaching part 7 with the attachment bolt which is not shown in figure.

  As shown in FIG. 8, the concave member 4 and the handrail holding member 3 coupled by the coupling bolt 51 and the nut 52 are first in a temporarily fixed state shown in FIG. 9, that is, the nut 52 is the male screw portion 513. The restriction main body guide portion 62 of the restriction member 6 is brought into contact with the fourth washer 54d and the fifth washer 54e. From this state, the handrail holding member 3 is slid with respect to the concave member 4 by hand against the elastic force of the elastic member 53, and the angle (direction) of the handrail holding member 3 with respect to the bracket body 2 is adjusted (for example, FIG. 9, the handrail holding member 3 is slid relative to the concave member 4 as indicated by a two-dot chain line in FIG.

  Thereafter, as shown in FIG. 9, the concave surface member 4 in the temporarily fixed state is fixed to the first concave surface member fixing portion 211 of the first bracket portion 21 of the bracket body 2. At that time, the handrail holding member 3 is maintained in a slidable state with respect to the concave member 4 by the elastic force of the elastic member 53. Therefore, by fixing the end 111 of the handrail 110 to the handrail holding member 3 in this state, the handrail 110 can be connected to the handrail bracket 1 while adjusting the angle of the handrail holding member 3.

  Next, the 2nd bracket part 22 is united with the 1st bracket part 21 with the main body connection bolt 23 (shown in FIG. 9).

  When the second bracket portion 22 is aligned with the first bracket portion 21 at the time of this uniting, the regulating member pressing portion 223 of the second bracket portion 22 abuts on the pressed portion 64 of the regulating member 6, although not illustrated. A gap is formed between the second bracket portion 22 and the first bracket portion 21.

  When the main body connecting bolt 23 inserted into the bolt insertion hole 213 of the first bracket portion 21 starts to be screwed into the female screw portion 221 of the second bracket portion 22, the second bracket portion 22 is moved to the first bracket portion 21. The restriction member pressing part 223 of the second bracket part 22 starts to press the pressed part 64 of the restriction member 6.

  When the regulating member 6 is pressed, the regulating body 61 of the regulating member 6 enters between the fourth washer 54d and the fifth washer 54e against the elastic force of the elastic member 53. At this time, since the thickness of the restricting main body 61 is thicker than the thickness of the restricting main body guiding portion 62, the elastic force of the elastic member 53 is increased and acts to push the gap L between the nut 52 and the concave member 4. Thereby, the connecting bolt 51 receives a force in the inward direction (X direction in FIG. 6) of the bracket main body 2, that is, the connecting bolt 51 moves in the X direction, and the handrail holding member 3 is concaved via the second washer 54b. It is pressed against the member 4. As a result, the handrail holding member 3 is in a fixed state where it cannot slide relative to the concave member 4. In this case, since the regulation main body guide portion 62 is formed so that the thickness gradually decreases from the regulation main body portion 61, the regulation main body portion 61 easily enters between the fourth washer 54d and the fifth washer 54e. Therefore, the temporarily fixed state can be easily changed to the fixed state.

  Accordingly, when the second bracket portion 22 is combined with the first bracket portion 21, the restriction main body portion 61 of the restriction member 6 enters a predetermined position between the fourth washer 54d and the fifth washer 54e and is held by handrails. The member 3 can be fixed to the concave member 4.

  As described above, according to the handrail bracket 1 of the present invention, the handrail holding member 3 is appropriately slid along the concave surface of the concave member 4 so that the handrail holding member 3 is adjusted to a predetermined angle with respect to the bracket body 2. In this state, if the restriction main body 61 of the restriction member 6 is interposed at a predetermined position between the nut 52 and the concave member 4, the force in the direction in which the handrail holding member 3 approaches the concave member 4 (FIG. 6). The force in the X direction) can be applied to the handrail holding member 3 via the connecting bolt 51, and as a result, the handrail holding member 3 and the concave member 4 can be connected in a fixed state. As a result, as in the prior art, in a state in which the handrail holding member is adjusted to a predetermined angle with respect to the bracket body, the operation of tightening the fastening nut with the tool on the fastening bolt that penetrates the handrail holding member and the concave surface member is performed. This can be eliminated, and the handrail bracket can be easily assembled.

  Further, since the restriction main body 61 is disposed at least on both sides of the shaft insertion hole 63 (that is, the coupling bolt 51), the force in the direction in which the handrail holding member 3 approaches the concave member 4 is restricted. It can be provided easily and reliably by the member 6.

  Further, before the restriction main body 61 of the restriction member 6 is disposed at a predetermined position by the elastic member 53, the handrail holding member 3 is appropriately slid with respect to the concave member 4 by the elastic force of the elastic member 53. In this state, the restriction main body 61 of the restriction member 6 can be disposed at a predetermined position. Further, after the restricting member 6 is disposed at a predetermined position, the elastic force of the elastic member 53 is increased, and the handrail holding member 3 can be further strongly biased in the direction approaching the concave surface member 4. The concave member 4 can be reliably fixed.

  In addition, when the first bracket portion 21 and the second bracket portion 22 are combined, the restriction member 6 can be pressed to a predetermined position by the restriction member pressing portion 223 of the second bracket portion 22. Thereby, the operation | work which presses the control member 6 to a predetermined position separately from the uniting operation | work of the 1st bracket part 21 and the 2nd bracket part 22 can be made unnecessary, and an assembly | attachment operation | work can be made easy.

  In the above-described embodiment, the nut 52 is the second retaining member of the present invention. However, the present invention is not limited to this configuration and can be changed as appropriate. For example, as shown in FIGS. 10 and 11, the second retaining member of the present invention may include a push nut 520 that is a locking member that is locked to the male screw portion 513 of the coupling bolt 51. Further, in the case where the second retaining member is constituted by such a retaining member such as the push nut 520, although not shown, as a shaft member of the present invention, a male screw portion and a head are used instead of the coupling bolt 51. A shaft member that does not have a portion may be used, and the first retaining member may be made of the same material as the push nut 520.

  Moreover, in the said embodiment, although the limitation member 6 can be rotated with respect to the coupling bolt 51 as a shaft member, it can change suitably not only in the thing of this form, and rotation of the limitation member 6 with respect to a shaft member. You may provide the rotation prevention part which blocks | prevents a movement. For example, the entire columnar portion 514 of the coupling bolt 51 as the shaft member is formed from a rectangular columnar portion 514a that cannot be rotated and can be inserted into the shaft insertion hole 63 of the restricting member 6. And the shaft insertion hole 63 of the restricting member 6 may constitute a rotation preventing portion, or the bracket body 2 may be provided with a rotation preventing portion for preventing the restricting member 6 from rotating relative to the shaft member. By providing such a rotation preventing portion that prevents the rotation of the restriction member 6 with respect to the shaft member, when the second bracket portion 22 is united with the first bracket portion 21, the restriction member pressing of the second bracket portion 22 is performed. The part 223 can surely press the pressed part 64 of the regulating member 6.

  Moreover, in the said embodiment, although the elastic member 53 was arrange | positioned between the limitation member 6 and the concave-surface member 4, it is not restricted to the thing of this form, and the elastic member 53 is the limitation member 6 and the nut 52 (No. 2 between the restricting member 6 and the nut 52, and between the restricting member 6 and the concave member 4, and can be changed as appropriate. Moreover, the thing of the form which does not provide the elastic member 53 may be sufficient.

  Further, in the above embodiment, the nut 52 is screwed to the male screw portion 513 provided at the tip portion of the shaft portion 512 of the coupling bolt 51, and the nut 52 is screwed to the root portion of the male screw portion 513. Thus, the distance L between the nut 52 and the concave member 4 is managed to some extent. Accordingly, the fixing strength of the handrail holding member 3 and the concave member 4 in the fixed state is kept substantially constant. However, the fixing strength may be more adjustable. That is, for example, the male screw part 513 is provided on the entire shaft part 512 of the coupling bolt 51 so that the screwing position of the nut 52 in the axial direction of the male screw part 513 can be changed in a wider range, that is, the nut 52 and the concave member 4. You may enable it to change the space | interval L with. According to this structure, the freedom degree of the said fixed strength in the said fixed state of the handrail holding member 3 and the concave surface member 4 improves, and it becomes possible to provide the handrail bracket 1 which is more practical and easy to use.

  Moreover, in the said embodiment, although the control member 6 is comprised from the 2nd bracket part 22 and a different thing, the control member 6 and the 2nd bracket part 22 may be connected, for example. That is, the restricting member 6 and the restricting member pressing portion 223 of the second bracket portion 22 are integrally molded, and the restricting member 6 receives the coupling bolt 51 when the first and second bracket portions 21 and 22 are combined. It may be formed in the shape of an inverted U shape having a groove portion capable of.

  Moreover, in the said embodiment, although the bracket main body 2 was comprised from the straight cylindrical body, it is not restricted to the thing of this form, For example, as shown in FIG. 12, about the handrail bracket 200 used for a corner part, The bracket body 202 may have a curved shape.
