  When a handrail bar is installed on such a true wall using the above-mentioned conventional handrail bracket, the bracket for the projected corner can be applied to the pillar arranged at the projected corner portion, which is particularly problematic. Does not occur.

  However, the supporting member cannot be attached to the pillars arranged in the corners. On the other hand, although the bracket for the projecting corner can be attached to the column, the orientation of the bracket body is reversed, so that it cannot be applied after all. On the other hand, it is possible to deal with new corner brackets, but it is not desirable to increase the types of brackets. Inappropriate brackets may be used by mistake or inventory management will be difficult. The inconvenience arises.

  Therefore, the present invention has been made in view of such a point, and the object of the present invention is to be able to satisfactorily install a handrail bar at the protruding corner portion and the entering corner portion of the true wall without increasing the types of brackets. It is to provide a handrail bracket.

  The handrail bracket according to the present invention is provided at the other end portion of the fixing member so that the front member can be reversed to the back side, the fixing member having one end that can be attached to the pillar of the protruding corner portion of the true wall, And a bracket body to which a handrail bar is attached, and the fixing member is configured to be attachable to a pillar at a corner of the true wall through a spacer.

  According to this, for example, when installing a handrail rod on a true wall having a protruding corner portion and an entering corner portion, one end portion of the fixing member is fixed to the column of the protruding corner portion and provided at the other end portion of the fixing member. Attach one end of the handrail bar to the bracket body. On the other hand, one end of the fixing member is fixed to the column at the corner of the entrance via a spacer. Furthermore, after the front part of the bracket body is inverted to the back side so that the other end part of the handrail bar can be attached, the other end part of the handrail bar is attached to the bracket body.

  In other words, if the handrail bracket for the corner is used in the corner portion with the front portion of the bracket body reversed to the rear side, the center axis of each bracket body does not match and the corner The bracket body on the side is shifted toward the front side with respect to the central axis. However, by fixing one end of the fixing member to the column at the corner of the entrance via a spacer having a predetermined thickness, the deviation between the central axes of both is eliminated. Thereby, it becomes possible to attach a handrail bar | burr favorably between both bracket main bodies, and a handrail stick | rod can be installed along a true wall. In this way, it is possible to share the handrail bracket at the exit corner and the entrance corner. Note that the “front surface of the bracket main body” here refers to a portion of the bracket main body that is located on the opposite side of the rear surface facing the true wall column.

  In addition, the bracket body may be formed in a substantially L shape so that a pair of handrail bars are attached to cross each other.

  According to this, the pair of handrail bars attached to the bracket body is attached in an intersecting state via the bracket body. Thereby, a handrail bar can be installed on the wall surfaces on both sides forming the protruding corner portion of the true wall.

  Further, the bracket body can be detachably or pivotably provided at the other end of the fixing member so as to invert the front surface portion of the bracket body to the back surface side.

  According to this, if the bracket main body is removed from the fixing member, or the bracket main body is rotated with respect to the fixing member, the front portion of the bracket main body can be easily reversed to the back side.

  Moreover, you may form the attachment surface fitted to the corner | angular part of a pillar in the one end part of the said fixing member.

  According to this, one end of the fixing member is attached to the column in a state where the mounting surface is fitted to the corner of the column. By fitting the attachment surface to the corner of the column, the fixing member can be securely and firmly attached to the desired position of the column.

  Furthermore, you may comprise the said fixing member so that it may have a base part which can be attached to a pillar, and an arm part which is provided in the front surface of this base part, and to which a bracket main body is attached.

  According to this, by providing the pedestal portion and attaching it to the pillar, the fixing member is firmly attached. Further, by attaching the bracket main body to the arm portion, the handrail bar attached to the bracket main body can be installed with a desired distance from the true wall.

  A spacer may be fixed to the fixing member.

  In this case, the fixing member is attached to the pillar at the corner of the true wall through the spacer. According to this, the bracket main body can be arranged on the front side by the thickness of the spacer. When the handrail bar is attached, it is possible to eliminate the displacement of the bracket body to which each end of the handrail bar is attached.

  As described above, according to the present invention, it is possible to share the handrail bracket for the protruding corner portion and the entering corner portion of the true wall, and it is possible to satisfactorily install the handrail rod on the true wall.

The bracket body 1 can be detached from the fixing member 5 by loosening the screw 6 and can be inverted 180 ° so that the front surface portion 1a of the bracket body 1 comes to the back surface side.

  The pedestal portion 5a of the fixing member 5 has a vertically long shape, and a substantially L-shaped mounting surface 7 that fits into a corner portion of the column is formed on the back surface portion thereof. Further, an inclined hole 8 that is inclined obliquely downward is formed on the upper front side of the pedestal portion 5a (see FIG. 3). Further, a mounting hole 9 is formed through the front lower portion in the front-rear direction. The tapping screws 22 and 23 are inserted into the inclined holes 8 and the attachment holes 9, and the pedestal portion 5 a is fixed to the column by the tapping screws 22 and 23. In this case, since the hole on the upper side is constituted by the inclined hole 8, when the tapping screw 22 is tightened with a tool such as a screwdriver, interference between the tool and the arm portion 5b of the fixing member 5 is avoided. It is possible and is very effective for work. In addition, in order to conceal the heads of the tapping screws 22 and 23, the synthetic resin cover bodies 10 are detachably fitted on the upper and lower portions of the front surface of the base portion 5a.

  The handrail bracket A used for the pillar at the corner portion of the true wall is configured as described above. Further, as shown in FIGS. 2 to 4, the handrail bracket B used for the pillar in the corner portion of the true wall has the spacer 30 attached to the mounting surface 7 of the pedestal portion 5a of the handrail bracket A for the outgoing corner. Is.

  That is, the front surface of the spacer 30 is formed so as to be fitted to the mounting surface 7 of the pedestal portion 5a. In this state, the screw 32 is inserted into the through hole 31 provided on the lower side of the spacer 30, and this is screwed into the screw portion 33 of the base portion 5a to be fixed. In addition, the spacer 30 is provided with an inclined hole 34 and an attachment hole 35 communicating with the inclined hole 8 and the attachment hole 9 of the pedestal portion 5a.

After that, the front end portion 1a of the bracket body 1 is positioned forward (opposite side of the column P), and the distal end portion of the arm portion 5b of the fixing member 5 is inserted into the arm portion insertion hole 4b. Fix it.

  Next, the case where a handrail bracket is fixed to the column Q of the corner portion Y of the true wall Z will be described. In this case, the pedestal handrail bracket A is swept away, and the base portion 5a of the fixing member 5 is fixed to the corner portion of the column Q in a state where the front portion 1a of the bracket body 1 is reversed to the back side. It is also possible. However, in this case, as shown in FIG. 6, a shift of L occurs in the front-rear direction between the central axes of the cylindrical portions 2 of the handrail brackets A respectively attached to the protruding corner portion and the entering corner portion. This cannot be used directly.

  Therefore, in this case, the cornering handrail bracket B is used. As shown in FIG. 5, the spacer 30 of the handrail bracket B is fixed to the corner portion of the column Q at the corner portion Y by tapping screws 22 and 23. The bracket main body 1 is detached from the arm portion 5b of the fixing member 5, and is again inserted into the arm portion 5b and fixed with screws 6 so that the back surface portion 1b is disposed on the front surface side. According to this, since the bracket main body 1 is arranged on the front side by the thickness of the spacer 30, the central axes of the cylindrical portions 2 of the bracket main bodies 1 substantially coincide with each other. As a result, the handrail bar 20 can be satisfactorily mounted between the handrail bracket A for the corner and the handrail bracket B for the corner.

  In this way, it is possible to share the handrail bracket A for the corner as the handrail bracket B for the corner by simply adding the spacer 30 having a simple configuration. As a result, only one type of handrail bracket itself is required, so that a situation of misuse does not occur and inventory management can be simplified.

  Further, since the handrail brackets A and B according to the present embodiment have a very simple overall configuration, there is also a practical advantage that they can be manufactured inexpensively and easily.

  In the above-described embodiment, the bracket body 1 is formed in a substantially L shape so that the pair of handrail bars 20 are attached so as to cross each other. However, when only one handrail bar 20 needs to be attached, the bracket body 1 may be formed in a substantially I-shape, for example. That is, the bracket body 1 can be arbitrarily changed according to the usage mode, and the specific shape is not questioned.

  Moreover, in the said embodiment, in order to reverse the front surface part 1a of the bracket main body 1 to the back side, this bracket main body 1 can be attached or detached freely to the other end part (the front-end | tip part of the arm part 5b) of the fixing member 5. Although provided, it is not always necessary to configure in this way. For example, the bracket body 1 may be rotatably provided at the other end of the fixing member 5. In this case, the bracket body 1 is rotated with respect to the fixing member 5 as necessary, and the front surface portion 1a is reversed to the back surface side.

  In the above embodiment, the fixing member 5 is composed of the pedestal portion 5a that can be attached to the pillar P and the arm portion 5b to which the bracket body 1 is attached. It is not limited.

  Further, the entrance corner handrail bracket B may be manufactured by fixing the spacer 30 to the exit corner bracket A in advance. According to this, the work at the site is simplified and a series of work can be performed efficiently. However, the spacer 30 may be fixed on site.

  In addition, the specific configuration such as the shape of the spacer 30 can be arbitrarily changed within the intended range of the present invention.
