Description

[Detailed Description of the Invention] The present invention relates to a handrail bracket that can be suitably used for a multi-stage handrail.

Conventional handrail fittings were developed for single handrails, and when used in multi-stage handrails, it is difficult to position each individual fitting, which requires time and effort to construct, and the joints of the handrail pipes are difficult to install. There was a defect that occurred between the metal fittings.

In addition, when constructing a custom-made multi-stage handrail using square pipes, in order to ensure sufficient strength of the handrail, square pipe supports must be erected from the floor slab to the members in the ceiling. Because the handrails are placed near the windows to make the area wider, notches are formed in the waste sash boards and curtain boards, which increases the production cost of the waste sash boards and curtain boards, and also lengthens the construction period. was there.

An object of the present invention is to provide a multi-stage handrail bracket that allows a multi-stage handrail to be easily and appropriately configured and has higher safety.

Next, the drawings will be explained.

FIGS. 1 and 2 show a conventional single-type handrail, in which each handrail pipe 1 is fixed by a respective mounting bracket 2, and is configured in three stages. In this conventional example, as described above, The drawback was that it took time to configure.

In addition, Fig. 3 shows a structure using conventional square pipes, and each handrail pipe 3 is attached to an appropriate position on a square pipe support 5 using screws 4, but in order to install the support, there is a scrap board 6 of the sash at the bottom of the support. In addition, the cutouts 8 and 9 must be provided in the upper curtain plate 7, respectively, resulting in the above-mentioned drawbacks.

The multi-stage handrail bracket 10 according to the present invention is shown in FIGS. 4 to 6.
As shown, it comprises a vertically arranged body 11, with an integral leg 12 at its upper end and a similar integral leg 13 at its lower end, the legs extending from the body 11 in the same direction. It stands out.

It is preferable that each leg protrudes at a right angle to the main body 11 as shown, but it goes without saying that it may be inclined.

Further, an integral locking plate portion 14 is provided at the tip of each leg 12.13, and each locking plate portion 14 is placed vertically like the main body,
This handrail bracket 10 is fixed by screws 16 to a member 15 such as a mullion or a column to which it is attached.

In addition, in some cases, a back reinforcing material 1 is attached to the back side of the member 15 to strengthen the member 15 and erect a tap that engages with the screw 16.
7 may be fixed.

Further, the main body 11 of the bracket is integrally provided with support portions 18 at appropriate intervals on the opposite side of the legs 12.13, and in the example shown, three support portions 18 are provided, but any other number of support portions 18 are provided. Good too.

A handrail pipe 20 is installed on these support parts with screws 19.

Therefore, the cross section of each support part 18 has a shape corresponding to the cross-sectional shape of the handrail pipe 20, and in most cases, the cross section is shaped like an arc, as shown in FIG. has a cross section of

As is clear from Fig. 5, the handrail bracket 1 of the present invention
0 can be configured as an intermediate handrail bracket HOa or as an end handrail bracket NOb.

As can be seen in the lower right corner of FIG.
can be configured so that they cannot be removed.

Furthermore, as shown in FIG. 5, the number of handrail pipes 20 may be two, and they can be installed selectively.

The main body 11 of the bracket preferably has an H-shaped cross section or a U-shaped cross section, as shown in FIG. 6, and the handrail bracket 10 is made by casting, forging, or the like.

In order to configure a multi-stage handrail using this handrail bracket 10, the locking plate part 14 at the end of the leg of the bracket is fixed to the sash mullion etc. with screws 16, the intermediate handrail bracket HOa is attached, and the end Similarly, handrail brackets 10b for the ends are attached to the sections and partitions.

Next, the handrail pipe 20 may be spliced or cut to a predetermined length, placed on the support portion 18 of each bracket 1 to 10, and fixed with screws 19.

Therefore, according to the present invention, a bracket with an integrated gear structure is provided, so there is no problem of positioning as in the past.
Further, there is no need to process waste sash boards or curtain boards, and a multi-stage handrail can be easily constructed.

Therefore, manufacturing costs can also be reduced. Furthermore, the pitch of the handrails and the number of handrails can be changed, so that it is possible to configure a handrail that matches the purpose of use.

Furthermore, it eliminates the anxiety caused by a single handrail and properly prevents falls to the outside, making it highly safe.
