By selecting the insertion hole 12, the fixing tool 11 can be prevented from protruding outside the wall surface 1a.

  The present invention provides a handrail bracket not only at the protruding corner of the wall where the headboard is not attached to the end, but also at the protruding corner of the wall where the headboard is attached to the end (that is, the protruding corner of the headboard). It fits well and can be securely and securely attached.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  The handrail bracket 6 of the present invention has a handrail rod 4 on the corner 2 of the wall 1 (the corner of the corner wall, the corner of the partition wall, the corner of the staircase, etc.). It is for installing.

  The handrail bracket 6 includes a bracket main body 6a, a bracket cover 6b, a base member 6c, and a reinforcing member 6d that constitute the main body.

  The bracket body 6a is as shown in FIG. 4 and is integrally formed by aluminum die-casting, so that one end portion of the body portion 15 becomes the base portion 16 and the other end portion holds and fixes the handrail rod 4. This is a handrail stick mounting portion 5. In the embodiment, the bracket cover 6b is made of synthetic resin, the base member 6c is made of aluminum die-cast, and the reinforcing member 6d is made of stainless steel.

  The body portion 15 is provided with a recess 17 that opens laterally.

  The base portion 16 is provided with a recessed portion 18 for fitting the base member 6c on the back surface. The base portion 16 is provided with a plurality of screw insertion holes 19 and a plurality of large diameter holes 20 as shown in FIG. The base member 6c fitted into the recessed portion 18 is as shown in FIG. 5, and the base member 6c has a screw hole 21 corresponding to the plurality of screw insertion holes 19 and a fixing corresponding to the large diameter hole 20. A tool insertion hole 12 is provided, and a screw tool 23 inserted from the screw insertion hole 19 in a state where the base member 6 c is fitted in the recessed portion 18 is screwed into the screw hole 21, and the base member 6 c is attached to the base portion 16. The wall fixing portion 9 is constituted by the base portion 16 which is fixed and to which the base member 6c is fixed.

  Here, the reinforcing member 6d is disposed in the recess 17 and is attached along the trunk portion 15, the base portion 16, and the handrail rod attaching portion 5. The attaching portion of the reinforcing member 6d is shown in FIG. As shown, the reinforcing member 6d, the base member 6c, and the bracket body 6a are inserted into the screw hole 21 through the screw insertion hole 19 by inserting the screw 23 from the hole 22 provided at one end of the reinforcing member 6d. It is stuck.

  A positioning projection 10 is integrally projected at a right angle from one end of the back surface of the base portion 16 of the wall fixing portion 9 toward the back. The protruding length of the positioning protrusion 10 is shorter than the wall fixing part 9. Further, the lateral length of the wall fixing portion 9 is shorter than the lateral width of the headboard 13 provided at the end of the wall 1 such as a partition wall or a staircase wall, which will be described later, and the protrusion length of the positioning projection 10 is the above-mentioned headboard. It is shorter than 13 thickness.

  As described above, the positioning projection 10 is protruded from one end of the wall fixing portion 9 and the protruding corner mounting portion 3 for mounting on the protruding corner portion 2 of the wall 1 is configured. Therefore, the protruding corner mounting portion 3 has an L shape in which one piece is long and the other piece is short, and the shorter positioning projection 10 is the other of the two surfaces 7 and 8 adjacent to each other through the protruding corner portion 2. The longer wall fixing portion 9 is in contact with one surface 7 of the two adjacent surfaces 7 and 8 through the protruding corner portion 2 and is inserted into the fixing tool. The fixing tool 11 is driven through the hole 12 to be fixed to the wall 1.

  Here, the fixing tool insertion hole 12 provided in the wall fixing portion 9 (that is, the fixing tool insertion hole 12 provided in the base member 6c in the embodiment) is connected to the fixing tool insertion hole 12 as shown in FIG. The inclined hole is inclined so that the tip in the insertion direction is away from the positioning protrusion 10 when the is inserted.

  The handrail rod mounting portion 5 has a cross-sectional arc shape with a curvature corresponding to the curvature of the handrail rod 4, and the peripheral portion of the handrail rod mounting portion 5 or the substantially entire surface of the handrail rod mounting portion 5 is connected to the receiving surface portion 5 a. Thus, a part of the handrail bar 4 having a circular cross section is received in the circumferential direction so that it can be received exactly. A positioning projection 24 projects from the handrail rod mounting portion 5 in a direction parallel to the axial direction of the handrail rod 4.

  Further, the handrail stick attaching portion 5 is provided with a plurality of fixing tool insertion holes 30. A fixing tool insertion hole 30 opens in the recess 17.

  The handrail rod 4 is attached to the handrail rod mounting portion 5 directly or via a protective cover 25 as shown in FIG.

  As shown in FIGS. 1 to 3, the protective cover 25 for protecting the end portion of the handrail bar 4 has a bottomed cylindrical shape with one end closed, and includes a cover main body 25a and a cover sub-body 25b. It is configured in combination.

  The cover main body 25a is formed by die casting of aluminum, and a disc-shaped bottom piece 33 is integrally provided at one end of a semicircular portion 27 having a semicircular cross section. Locking portions 34 are provided on the outer surface portions at both ends in the circumferential direction. The cover sub-body 25b is made of a synthetic resin and has a semicircular cross section. Locked portions 35 are provided on inner surface portions of both ends in the circumferential direction of the semicircular cover sub-body 25b. A semicircular shape is obtained by engaging both ends in the circumferential direction of the cover sub-body 25b with both ends in the circumferential direction of the semicircular portion 27 of the cover main body 25a and locking the locked portion 35 to the locking portion 34. The cylindrical portion is constituted by the portion 27 and the semicircular cover sub-body 25b, and one end of the cylindrical portion is closed by a disk-shaped bottom piece portion 33, and thereby one end portion is closed. The protective cover 25 is configured.

  Here, the reason why the protective cover 25 is configured by combining two members of the cover main body 25a and the cover sub-body 25b is as follows. That is, when the bottomed cylindrical protective cover 25 whose one end is closed is to be molded by die casting or injection molding, the inside of the cylindrical portion of the bottomed cylindrical protective cover 25 has a draft angle for die cutting. For this reason, the inner diameter of the cylindrical portion becomes larger toward the opening end side, and when the one formed in this way is fitted on the handrail rod 4, the opening edge of the cylindrical portion and the handrail rod However, if the cover main body 25a and the cover sub-body 25b are combined as described above, the inner diameter of the cylindrical portion is as follows. When it is the same at each part in the axial direction and is fitted on the handrail bar 4, no small gap is generated between the opening edge of the cylindrical part and the outer surface of the handrail bar 4.

  An opening window 36 is provided in the middle portion of the semicircular portion 27 of the cover main body 25 a in the circumferential direction, and the periphery of the opening window 36 is a sandwiched portion 37. The outer surface of the sandwiched portion 37 around the opening window 36 is recessed from the outer peripheral surface of the protective cover 25 to form a fitting recess 38, and thus the outer surface of the sandwiched portion 37 is used as the protective cover 25. By being recessed from the outer peripheral surface, the thickness of the sandwiched portion 37 is made thinner than the thickness of other portions of the protective cover 25.

  In the handrail bracket 6 having the above-described configuration, after attaching the handrail bracket 6 to the protruding corner portion 2 of the wall 1 at a predetermined interval, the end portion of the handrail rod 4 fitted with the protective cover 25 is attached to each handrail bracket 6. A plurality of handrail brackets with the handrail brackets 6 attached to both ends of the handrail rod 4 with the protective covers 25 fitted on both ends. 6 is attached to each of the protruding corners 2 of the wall 1.

  FIG. 1 shows a protruding corner portion 2 of a wall 1 (that is, a protruding corner portion of the headboard 13) provided with a headboard 13 at an end portion, such as a protruding corner portion of the end portion of the partition wall and a protruding corner portion of the end portion of the staircase wall. 2) shows an embodiment in which the handrail bracket 6 is attached.

  As shown in FIG. 1, the handrail bracket 6 is attached to the protruding corner 2 of the wall 1, among the two surfaces 7 and 8 adjacent to each other via the protruding corner 2 (that is, the protruding corner 2 of the headboard 13). The handrail bracket 6 is attached to the headboard 13 by bringing the wall fixing portion 9 into contact with the front surface of the headboard 13 that is one surface 7 and hooking the positioning projection 10 in contact with the side end surface of the headboard 13 that is the other surface 8. Is positioned at the corner 2 of the In this case, since the positioning projection 10 has a short projection length and is intended to be hooked and positioned on the side end surface of the headboard 13, the tip of the positioning projection 10 is stored so as not to jump out beyond the side end surface of the headboard 13. Can do. In this manner, with the handrail bracket 6 positioned at the corner 2 of the headboard 13 at the end of the wall 1, the fixture 11 is inserted into the wall 1 from the fixture insertion hole 12 provided in the wall fixing portion 9. It sticks by driving.

  Here, in the present invention, since the fixing tool insertion hole 12 is an inclined hole, the fixing tool 11 inserted and driven into the fixing tool insertion hole 12 is inclined so as to be away from the positioning projection 10 toward the tip. Drive into the wall 1. Therefore, even if the side end portion of the headboard 13 protrudes from the wall surface 1a of the wall 1 as shown in FIG. 1, the fixing tool 11 is inclined from the fixing tool insertion hole 12 which is an inclined hole, and the width of the wall 1 is increased. It can be driven toward the central portion of the direction, and can be firmly and firmly fixed by the fixing tool 11. Further, the position of the wall surface 1a with respect to the side surface of the headboard 13 may be different at the site as shown in FIG. 1B, but the protruding length differs from the wall surface 1a of the side wall 1 of the headboard 13 in this way. However, the fixing tool 11 can be reliably driven into the wall 1 toward the center portion in the width direction of the wall 1.

  Further, the position of the wall surface 1a with respect to the side surface of the headboard 13 is longer than the wall surface 1a of the wall 1 at the side end of the headboard 13 at the site as shown in FIG. Since a part of the fixing tool 11 driven obliquely from the tool insertion hole 12 may be exposed to the outside of the wall 1, in this case, the fixing tool 11 starts from the fixing tool insertion hole 12 closest to the positioning protrusion 10. Without fixing, the fixing tool 11 is driven and fixed from the other fixing tool insertion hole 12. That is, the fixing tool 11 indicated by the symbol A in FIG. 1 is not driven. Although not shown, when the thickness of the wall 1 is short, when the fixing tool 11 is driven obliquely from the fixing tool insertion hole 12 farthest into the positioning protrusion 10, the tip of the fixing tool 11 protrudes out of the wall 1. There is a risk that. Therefore, in such a case, the fixing tool 11 is not driven from the fixing tool insertion hole 12 farthest into the positioning protrusion 10, and the fixing tool 11 is driven and fixed from the other fixing tool insertion hole 12. As described above, in the present invention, a plurality of fixing tool insertion holes 12 are provided in the wall fixing portion 9 in a direction orthogonal to the protruding direction of the positioning protrusion 1010. Therefore, the plurality of fixing tool insertion holes 12 are selected. By driving the fixing tool 11 obliquely, it is possible to cope with a site where the protruding length from the wall surface 1a of the side wall 1 of the headboard 13 is long, or a site where the thickness of the wall 1 is short.

  In the embodiment shown in the accompanying drawings, as described above, the fixing tool 11 is inserted obliquely from the fixing tool insertion hole 12 made of the inclined hole provided in the base member 6c and fixed to the wall 1. That is, the bracket body 6a is not directly attached to the wall 1 with the fixing tool 11, but the bracket body 6a is indirectly attached by attaching the base member 6c attached to the bracket body 6a with the screw tool 23 to the wall 1 with the fixing tool 11. As a result, the bracket body 6a can be removed with the base member 6c remaining on the wall 1 by removing the screw 23, such as when the bracket body 6a is damaged. By attaching to the base member 6c using the tool 23, there is no need to remove the fixing tool 11.

  The handrail bar 4 is provided with a positioning recess 26 on the outer surface in the longitudinal direction, and a protective cover 25 is fitted on the end of the handrail bar 4. With the protective cover 25 fitted on the end of the handrail rod 4, the positioning projection 24 that protrudes from the handrail rod mounting portion 5 is brought close to the handrail rod mounting portion 5 of the handrail rod 4. In this state, the protective cover 25 is slightly turned in the circumferential direction so that the receiving surface portion 5a of the handrail rod mounting portion 5 is inserted into the recessed portion 38. The receiving surface portion 5 a is brought into contact with the sandwiched portion 37 by being fitted.

  In such a state that the handrail bar 4 and the handrail bracket 6 are positioned with the handrail bar mounting portion 5 and the protective cover 25 fitted to the end of the handrail bar 4 and the handrail bracket 6 are positioned. The handrail stick attaching portion 5 can be attached to a predetermined position in the circumferential direction of the handrail bar 4 by inserting the sticker 11 from each of the plurality of fastener insertion holes 30 and fixing it to the handrail bar 4. When the fixing tool 11 is fixed as described above, the sandwiched portion 37 around the opening window portion 36 of the protective cover 25 is sandwiched between the handrail rod 4 and the receiving surface portion 5a, and the protective cover 25 is secured to the handrail rod 4 and the hand. It is held and fixed to the sliding bracket 6.

  Here, in the attachment portion of the reinforcing member 6d, the fixing tool 11 is inserted from the hole 29 provided at the other end of the reinforcing member 6d and is fixed to the handrail rod 4 through the fixing tool insertion hole 30. The handrail bar 4 is fixed to the bracket body 6a and the reinforcing member 6d by the fixing tool 11, and the reinforcing member 6d is fixed to the base member 6c by the screw tool 23 as described above. Since the member 6c is fixed to the wall 1, even if the aluminum die-cast bracket body 6a is damaged by an external force, the handrail bar 4 is fixed to the wall 1 via the stainless steel reinforcing member 6d and the base member 6c. Thus, the handrail bar 4 can be prevented from being detached from the wall 1.

  The bracket cover 6b is detachably attached to the opening of the recess 17 of the bracket body 6a to cover the recess 17.

  In the above embodiment, the protective cover 25 is fitted to the end of the handrail bar 4 and the end of the handrail bar 4 is attached to the handrail bracket 6 via the protective cover 25. The handrail bar 4 may be directly attached to the handrail bracket 6 without fitting the protective cover 25.

  In the above-described example, an example in which the handrail bar 4 is attached by the handrail bracket 6 to the protruding corner portion 2 of the wall 1 provided with the headboard 13 at the end is shown.
