Description

[Detailed Description of the Invention] The present invention relates to an improvement of a handrail bracket for supporting a handrail disposed on a wall surface such as a wall.

Conventionally, this type of handrail bracket has been made up of a collar-shaped mounting base that is fixed to a wall surface and a support part that projects from the surface side of this mounting base and supports the handrail body. Regardless of whether the material of the wall to be mounted is concrete, wood, etc., the usual method for installing a bracket is to insert an anchor bolt, which has been previously installed at a predetermined location on the wall surface, into the approximate center of the mounting base. The handrail bracket was fixed to the wall surface by inserting the bolt into the through hole and screwing and locking the anchor bolt with a nut.

However, such conventional handrail brackets are installed using anchor bolts regardless of the material of the wall surface, but the installation work of handrail brackets using these anchor bolts is difficult. It is relatively troublesome to install anchor bolts on the wall, especially if the wall material is made of wood and can be nailed. There was a strong desire to simplify the installation process.

The present invention was developed based on the above-mentioned viewpoint, and its purpose is to provide a suitable number of guide recesses on the periphery of the back surface of the mounting base to form a thin wall part, so that the wall material can be made of wood. etc., where nailing is possible, it is possible to drill through the thin-walled part and insert fasteners such as nails, which simplifies the installation work of the handrail bracket, and also allows the wall material to be installed easily. Our objective is to provide a handrail bracket that does not impair the appearance quality in cases where nailing is not possible due to concrete acid etc. (It is possible to install using conventional anchor bolts) .

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

In the embodiment shown in FIGS. 1 to 3, the handrail bracket B includes a flange-shaped mounting base 2 that is fixed to a wall surface 1, and a handrail body 3 that protrudes from the surface side of this mounting base 2. The supporting portion 4 is integrally formed using aluminum or the like.

In the above embodiment, the mounting base 2 is composed of a substantially rectangular collar 5 that contacts the wall surface 1 and a protrusion 6 that projects laterally at the center of the front surface of the collar 5. There it is,
A bolt through hole 7 that passes through the protrusion 6 and the collar 5 is bored in the approximate center of the mounting base 2. The bolt through hole 7 is stepped in the middle, and the mounting base 2 The bolt through hole 7 on the front surface side is formed to have a large hole diameter.

As shown in FIGS. 2 and 3, a circular guide recess 8 is formed on the back surface of the mounting base 2, that is, on the upper edge and approximately in the center of both left and right side edges of the back surface of the collar portion 5. A thin portion 9 is formed between the bottom surface of the guide recess 8 and the surface of the flange portion 5 .

Further, the support portion 4 is formed into two parts that protrude upward from the tip of the protrusion 6 of the mounting base 2, and the tip of the support portion 4 has a substantially rectangular cross section extending substantially parallel to the wall surface 1. A supporting piece 10 is formed, and this supporting piece 10 is adapted to fit into a groove 12 of a guide rail 11 of the handrail body 3.

Furthermore, the handrail body 3 attached to the support part 4 includes a guide rail 11 having a U-shaped cross section and a groove 12 on the lower side, and a synthetic resin covering attached to cover the guide rail 11. The covering body 13 is fitted onto the guide rail 11 in a state where it bites into notches 14 formed on both sides of the guide rail 11.

As shown in FIGS. 1 and 2, this handrail body 3 is constructed by fixing a handrail bracket B to an appropriate location on the wall surface 1 in advance, and supporting pieces 10 formed on the support portion 4 of this handrail bracket B. After covering the guide rail 11 from above so that the groove 12 of the guide rail 11 fits into the groove 10, and fixing the guide rail 11 and the support piece 10° 10 from the side of the guide rail 11 with screws, The covering body 13 is fitted to the guide rail 11 and the handrail bracket B
Fixed.

Therefore, according to the handrail bracket according to this embodiment,
As shown in FIGS. 2 and 4, when the wall material W is made of wood and the handrail bracket B is fixed to the wall surface 1, a thin wall portion 9 formed on the flange 5 of the mounting base 2 In,
An insertion hole 16 corresponding to the diameter of the nail 15 is bored, and the insertion hole 1
6, a fastener such as a nail 15 or a screw may be driven into the wall material W.

In addition, in FIG. 2, 17 is a furring provided on the back surface of the wall material W.

Furthermore, as shown in FIG. 5, when the wall material W is made of concrete and nailing is not possible, the handrail bracket B can be installed by attaching the anchor through the bolt through hole 7 of the installation base 2. This is done using bolt 18,
The anchor bolt 18 in this embodiment has a base formed by joining a locking piece 18a to a bolt 18b in a rotatable manner. and wall material W mounting hole 30
Hold the handrail bracket B on the wall surface 1 in a state in which the handrail brackets B are aligned with each other, and then insert the anchor bolts 18 with the nuts 19 previously attached to the threaded portions 18c from the surface side of the mounting base 2 into the bolt through holes 7 and the wall material W. is inserted into the mounting hole 30 of the bolt, and when the locking piece 18a is locked to the back surface of the wall material W as shown in FIG. This is done by tightening them until they touch.

In this case, as in the conventional case, anchor bolts 18 are installed in the wall surface 1 in advance, and the handrail bracket B is attached by inserting and locking the anchor bolts 18 into the bolt through holes 7 of the mounting base 2. Of course it's a good thing.

In addition, in FIG. 5, 21 is a blind plug for concealing the inside of the bolt through hole 7.

At this time, since the back surface of the mounting base 2 is in close contact with the wall surface 1, the guide recess 8 formed on the back surface of the mounting base 2 is not visible from the outside, and there is no need to drill an insertion hole 16 in the thin wall portion 9. , the appearance quality of the handrail bracket B is prevented from being impaired.

In the above embodiment, the guide recesses 8 are formed individually on the periphery of the back surface of the mounting base 2, but the guide recesses 8 are not necessarily limited to this. A guide recess 8 may also be formed.

In addition, in the above embodiment, the present invention is applied to the handrail bracket B in which the mounting base 2 and the support part 4 are integrally formed, but the present invention is applied to the handrail bracket B in which the mounting base 2 and the support part 4 are integrally formed. Handrail bracket B1 with adjustable distance For example, as shown in FIG. A cylindrical adjuster 25 that has a female threaded portion 22 and a male threaded portion 23 that is screwed into the female threaded portion 22 and has a female threaded portion 24 inside is attached to the mounting base 2, and the fixing bolt 26 is inserted into the female threaded portion of the adjuster 25. Of course, the present invention may also be applied to a handrail bracket B in which the support part 4 is fixed to the mounting base 2 by screwing into the handle 24.

Further, in the above embodiment, the support piece 10 of the support part 2 is formed to have a rectangular cross section, but for example, as shown in FIGS. 7 and 8, the support piece 10 may be formed to have a T-shaped cross section. In the case where the flange portions 27 of the waist are respectively provided to protrude in the longitudinal direction of the support piece 10 and the attachments 28 are provided in the protrusions flange portions 27, the flange portions 27 correspond to the cross-sectional shape of the support piece 10. After forming the handrail body 3 by fitting the cover 13 in advance to the guide rail 11 having the groove 12, the handrail body 3 is slid so that the groove 12 of the guide rail 11 fits into the support piece 10. It is attached to the handrail bracket B, and then the handrail bracket B and the handrail body 3 can be fixed with screws 29 from below the handrail body 3 through the attachment hole 28 of the support piece 10.

That is, the flange portion 27 of the support piece 10 and the guide rail 11
The handrail body 3 is regulated in its vertical position with respect to the handrail bracket B by the fitting state with the groove 12 of the handrail body 3. It does not move upwards, making installation easier.

As explained above, according to the handrail bracket according to the present invention, an appropriate number of guide recesses are provided on the periphery of the back surface of the mounting base to form a thin wall part, so even if the wall material is made of wood or the like, nailing work is not required. If this is possible, the thin-walled part can be drilled without using anchor bolts to allow fasteners such as nails to pass through, simplifying the installation work, and if the wall material is made of concrete, etc. If nailing is not possible, it is possible to install using anchor bolts in the same way as in the past, without exposing the guide recess to the outside and maintaining the appearance quality.
