  However, with regard to the conventional handrail bracket, it is only disclosed that the cover body is attached to the opening of the bracket body, and the cover body can be easily and reliably attached to the opening of the bracket body. In addition, it has been desired to develop a mounting means having a simple configuration.

  Moreover, although the said bracket main body is fixed to a wall surface via the flat mounting seat provided in the edge part, the thickness of this mounting seat is not fully ensured. For this reason, when fixing to a wall surface with a screw, the screw had to be fixed to the wall surface while holding both the bracket body and the screw, and the work at the site was very troublesome.

  Therefore, the present invention has been made in view of this point, and an object of the present invention is to provide an attachment means that can easily attach the bracket body and the cover body.

  The handrail bracket according to the present invention has an opening on the front surface, a handrail bar attached to one end, and a bracket body whose other end is fixed to a wall surface, and a removably attached to the opening. And a cover hole formed in one end portion of the bracket body to engage the engagement portion provided in the cover body, and provided in the cover body at the other end portion of the bracket body. A locking portion capable of locking the locking piece is formed.

  According to this, for example, after attaching a handrail bar to one end of the bracket body and fixing the other end to the wall surface, the bracket body is engaged with the engagement portion of the cover body in the engagement hole of the bracket body. The locking piece of the cover body is locked to the locking portion. Thereby, a cover body can be easily attached so that the opening part of a bracket main body may be covered. On the other hand, after releasing the locking state between the locking portion of the bracket body and the locking piece of the cover body, the cover body is removed from the bracket body by removing the engaging portion of the cover body from the engaging hole of the bracket body. It is also possible to remove it.

  Further, the cover body may be made of synthetic resin and the locking piece may be integrally formed.

  According to this, since the locking piece is integrally formed with the cover body, there is no need to separately attach the locking piece to the cover body, and if the locking piece is locked to the locking portion of the bracket body, the cover body Can be attached to the bracket body.

  Furthermore, the cover body may be made of metal, and a locking member provided with a locking piece may be detachably provided on the cover body.

  Thereby, when attaching a cover body to a bracket main body, what is necessary is just to attach a locking member to this cover body, and to lock the locking piece to the locking part of a bracket main body.

  As described above, the bracket body can be shared by unifying the means for attaching the cover body to the bracket body regardless of the material of the cover body. As a result, it is not necessary to separately manufacture a bracket body according to the material of the cover body, and inventory management can be simplified.

  Further, a cylindrical portion fixed to the wall surface may be provided at the other end portion of the bracket body, and a cylindrical body through which a rod-shaped fixing tool for fixing to the wall surface is inserted may be provided in the cylindrical portion. I do not care.

  According to this, a cylindrical part will be fixed to a wall surface with the rod-shaped fixing tool penetrated by the cylinder. In this case, since the fixing tool is maintained in the inserted state by the cylindrical body, the operator can perform the fixing work without holding the fixing tool. As a result, work efficiency can be improved.

  Moreover, since the handrail bracket according to the present invention has a very simple overall configuration, it can be manufactured easily and inexpensively.

  As described above, according to the present invention, the cover body can be easily attached to the bracket body.

  Hereinafter, an embodiment of a handrail bracket according to the present invention will be described based on the drawings.

  FIG. 1 shows a handrail bracket according to the present embodiment, where FIG. 1 (a) is a front view and FIG. 1 (b) is a side view. As shown in FIG. 2, the handrail bracket 1 is made of a metal bracket body 3 having an opening 2 formed on the front surface and a synthetic resin made detachably provided on the bracket body 3 so as to cover the opening 2. And a cover body 30.

  A wide engaging hole 5 is formed on one end side of the inner wall surface 4 located in front of the bracket body 3. In addition, a pair of mounting holes 6 are provided at a lower position with a predetermined interval in the vertical direction. As shown in FIG. 3, a cylindrical portion 7 into which a round bar-shaped handrail rod 50 is inserted is provided at one end on the back side of the bracket body 3. As shown in the figure, the handrail bar 50 is fixed by fastening a tapping screw 8 inserted through the mounting holes 6 and 6 to the front end surface thereof.

  As shown in FIG. 2B, three fixing holes 10 are provided on the bottom surface 9 of the opening 2 of the bracket body 3. Further, a groove portion 11 having a predetermined width is formed at the center front position, and a convex locking portion 13 is continuously provided at an inner portion of the groove portion 11 via an inclined surface portion 12 that is inclined higher toward the inner side. . As shown in FIG. 3, a cylindrical tubular portion 14 fixed to the wall surface A is provided at the other end portion of the bracket body 3. Further, the cylindrical portion 14 is provided with a plurality of cylindrical bodies 16 provided with circular holes 15 communicating with the fixing hole 10, and the cylindrical bodies 16 are predetermined in the axial direction (vertical direction in FIG. 3). The length is secured. Specifically, the length of the cylindrical body 16 is set to be twice or more the outer diameter of the tapping screw 17 inserted through the fixing hole 10 and the circular hole 15.

  In addition, the back surface part 14a located in the back surface side of the cylindrical part 14 of the bracket main body 3 is formed by extending the inner wall surface 4 as shown in FIG. Thereby, since the intensity | strength of the cylindrical part 14 improves, it becomes possible to maintain a favorable attachment state with the wall surface A over a long period of time.

  As shown in FIG. 3, an engaging portion 31 that can be freely engaged with and disengaged from the engaging hole 5 of the bracket body 3 is formed at one end on the inner surface side of the cover body 30. Further, a convex portion 32 that can be locked to the locking portion 13 of the bracket body 3 in a state where the engaging portion 31 is engaged with the engaging hole 5 of the bracket body 3 at the other inner surface side of the cover body 30. A locking piece 33 provided at the tip is provided. The engaging portion 31 and the locking piece 33 are formed integrally with the cover body 30.

  The cover body 30 does not necessarily need to be made of synthetic resin in this way, and can be made of metal. In this case, as shown in FIG. 4, the locking member 40 formed separately from the cover body 30 is attached to the cover body 30. Such a locking member 40 is formed in a substantially L-shaped side surface as shown in FIG. At one end portion, similarly to the synthetic resin locking piece 33, a locking piece 42 having a convex portion 41 that can be locked to the locking portion 13 of the bracket body 3 is provided at the tip. Further, as shown in FIG. 5A, the other end portion is provided with a pair of sandwiching pieces 44 and 44 having locking claws 43 on the inner surface of the tip portion, and is made of synthetic resin.

  On the other hand, as shown in FIG. 4, a mounting seat 45 to which the locking member 40 can be attached is integrally provided at the other end on the inner surface side of the cover body 30. The mounting seat 45 includes a base end portion 46 held by the holding pieces 44, 44 of the locking member 40, and a detachment formed at the tip thereof toward the other end side (lower side in FIG. 4). It consists of a prevention part 47. By pressing the holding pieces 44, 44 of the locking member 40 while facing the base end portion 46 of the mounting seat 45, the locking member 40 can be easily attached to the cover body 30.

  Thus, it is possible to share one type of bracket body 3 by unifying the means for attaching the cover body 30 to the bracket body 3 regardless of the material of the cover body 30. As a result, it is not necessary to separately manufacture the bracket body 3 according to the material of the cover body 30, and the inventory management can be simplified.

  Next, the case where the handrail rod 50 is installed on the wall surface A using the handrail bracket 1 will be described. In this case, a pair of handrail brackets 1 is used, but the cover body 30 is removed from the bracket body 3.

  First, as shown in FIG. 3, one end of the handrail bar 50 is inserted into the cylindrical portion 7 on one end side of one bracket body 3. In this state, the tapping screws 17 are inserted into the fixing holes 10 and the circular holes 15 provided in the bottom surface 9 of the bracket body 3, and are fastened to the wall surface A to be fixed. In this case, since the cylindrical body 16 in which the circular hole 15 is formed is formed with a predetermined length in the axial direction, when the tapping screw 17 is inserted therethrough, the hand is released from the tapping screw 17. However, the insertion state is maintained. Therefore, when the tapping screw 17 is fastened, the operator does not need to hold the tapping screw 17 by hand, and the work at the site can be performed efficiently. In addition, it is preferable to make a hole for the tapping screw 17 in the wall surface A in advance.

  Next, the tapping screw 8 is inserted into the mounting holes 6, 6 provided in the inner wall surface 4 of the bracket body 3 and fastened to fix the handrail rod 50 to the cylindrical portion 7 of the bracket body 3. The other end of the handrail rod 50 is fixed to the other bracket body 3 in the same manner.

  Thereafter, when the other end portion of the cover body 30 is pressed toward the bracket body 3 in a state where the engagement portion 31 of the cover body 30 is engaged with the engagement hole 5 of the bracket body 3, the locking piece 33 becomes the bracket body 3. The inclined portion 12 is pressed and bent, and the convex portion 32 of the locking piece 33 is locked to the locking portion 13 of the bracket body 3. Such a cover 30 can be attached to the opening 2 of the bracket body 3 very simply.

  On the other hand, when removing the cover body 30 from the bracket body 3, the groove 11 formed in the bracket body 3 may be used as shown in FIGS. 1, 3, and 4. That is, when a screwdriver or the like is inserted into the groove 11 and the cover body 30 is pressed to the near side, the locking state between the convex portions 32 and 41 of the locking pieces 33 and 42 and the locking portion 13 of the bracket body 3 Will be canceled. Then, if the engaging portion 31 of the cover body 30 is detached from the engaging hole 5 of the bracket body 3, the cover body 30 can be easily removed. Therefore, for example, the tapping screws 8 and 17 can be easily retightened and replaced.

  In the above embodiment, the cylindrical portion 14 is provided at the other end of the bracket body 3, but the cylindrical portion 14 is not necessarily provided and may be omitted. In this case, what is necessary is just to fix to the wall surface A directly via the bottom face 9.

  Moreover, when the cover body 30 is comprised with a metal, the latching member 40 can also be comprised with a metal. In this case, the locking piece 42 may be formed of, for example, a metal spring piece having elasticity.

  Furthermore, in the said embodiment, although the bracket main body 3 is being fixed to the handrail rod 50 and the wall surface A with the tapping screws 8 and 17, this fixing tool is not limited to this at all. For example, a nail or the like can be applied as a fixture.

  In addition, the shape and material of the bracket body 3 and the cover body 30 can be arbitrarily changed within the range intended by the present invention.

  As described above, the present invention is useful for a handrail bracket that attaches a handrail bar to a wall surface such as a hallway or a staircase.
