Description

[Detailed explanation of the idea]

[Field of Industrial Application] The present invention relates to a handrail bracket used for arranging a handrail cap on a support.

[Conventional technology]

When forming a handrail by arranging handrail caps on handrail supports erected at predetermined intervals on the floor of a balcony or hallway, fix the handrail caps that are continuous in the length direction onto the handrail supports. A handrail bracket is used for the purpose of holding a handrail or connecting multiple handrail caps, and conventionally, as shown in FIG. It has been proposed that a bracket body 3 and a bracket cover 4 that presses down and fixes the handrail cap 1 from above are supported by screws 5, 5 from both sides of the handrail.

[Problem that the invention attempts to solve]

However, these handrails are placed at the outer end of the balcony, so installation work must be done only from one side of the handrail, that is, the indoor side, and screwing from the outdoor side may result in an unnatural working posture. Being forced to do so led to poor work efficiency, and there were also safety issues when working at heights. The present invention has been developed in response to the above-mentioned circumstances, and an object of the present invention is to provide a handrail cap bracket 1 with high efficiency in installation work.

[Means to solve the problem]

According to the present invention, the above object is achieved by, as shown in FIG. An engagement groove 6 having a U-shaped cross section is formed along the side, and a dovetail engagement groove 7 is formed at the other free end located on the outdoor side, and is attached to the upper end of the handrail post 2. The bracket main body 3 on which the handrail cap 1 is placed and supported has an engaging protrusion 8 having a U-shaped cross section along the longitudinal direction on one side wall located on the indoor side, and an engaging protrusion 8 having a U-shaped cross section on the other side wall located on the outdoor side. Engagement ridges 9 having a dovetail cross section are provided on the side walls in a longitudinal direction, and the dovetail engagement ridges 9 formed on the bracket body 3 located on the outdoor side are connected to the bracket cover 4. The U-shaped engagement protrusion 8 of the bracket main body 3 located on the indoor side and the U-shaped engagement groove 6 of the bracket cover 4 are inserted into and engaged with the dovetail-shaped engagement groove 7 of the bracket cover 4. This is achieved by providing a Kasagi bracket characterized by engaging and screwing and fixing with screws 80.

[Effect]

That is, the present invention aims to improve installation efficiency by making it possible to fix the Kasagi bracket only from one side of the handrail.

【Example】

A preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings. Fig. 2 shows a handrail installed using the cap bracket of the present invention. In the figure, 20 is a floor of a balcony or the like, 2 is a handrail support pillar installed at a predetermined interval on the floor 20, and 21 is a handrail support pillar 2.
A handrail unit is supported between the handrail posts 1 and 2.
The handrail capping 1 of this embodiment is made by applying a resin coating 12 to the outer surface of a steel pipe 11 as shown in Fig. 1 and Fig. 3, and is formed with a circular cross section. The bracket body 3 on which the handrail capping 1 is placed and supported has two fixed legs 31, 31 on the back surface of a shield plate 30 that closes the upper end opening 22 of the handrail post 2.
These fixing legs 31, 31 are fitted into the upper end opening 22 of the handrail post 2 and fixed to the handrail post 2 by fastening with screws. A support part 32 is formed on the upper part of the shielding plate 30 of the bracket body 3, the upper surface of which is an arc-shaped surface that approximately matches the curvature of the handrail cap board 1.
A pair of engaging protrusions 8, 9 are provided on the side wall of the handrail cap board 1 in the direction of installation. These engaging protrusions 8, 9 engage with engaging grooves 6, 7 of the bracket cover 4, which will be described later, to secure the bracket cover 4 in place.
The side wall that is to be positioned on the outdoor side when installed is formed in a roughly dovetail shape, while the other side wall, that is, the side that is to be positioned on the indoor side when installed, is formed in a U-shaped cross section, and a screw hole 81 is drilled in the engagement protrusion 8 having a U-shaped cross section. The bracket cover 4 is an inverted U-shaped member with the curvature of the bent portion 40 roughly matching the curvature of the handrail cap board 1, and its free end is provided with a dovetail-shaped engagement recess 7 corresponding to the engagement protrusions 8, 9 of the bracket body 3.
The engaging protrusion 8 has a screw hole 81 and a screw insertion hole 60 formed in the engaging protrusion 8 at a position that matches the screw hole 81.
After the bracket body 3 is fixed to the upper end, the handrail cap board 1 is supported by the arc-shaped surface of the bracket body 3.
The handrail capping 1 can be fixed by sliding the engaging grooves 6, 7 over the engaging protrusions 8, 9 of the bracket body 3 in the longitudinal direction of the handrail capping 1, i.e., the direction shown by the chain line in FIG. 1, and then screwing the screw 80 into the screw hole 81. Therefore, if the engaging protrusion 8 having a U-shaped cross section of the bracket body 3 is positioned facing the indoor side,
Screwing can be done only from the indoor side, and there is no need to do work from the outdoor side. At this time, the dovetail-shaped engagement groove 7 and the corresponding dovetail-shaped engagement protrusion 9 are engaged on the outdoor side, so the free end of the bracket cover 4 does not shift outward.
The free end of the bracket cover 4 is fixed securely by the screw as shown in FIG.
When it is pushed in the direction, the slope of the dovetail-shaped engaging recess 7 presses against the slope of the engaging protrusion 9, effectively preventing rattling of the handrail capping 1. Although the above description has been of a capping bracket that is compatible with a handrail capping 1 having a circular cross section, it is of course possible to make it compatible with various handrail cappings 1 by changing the bent portion 40 of the bracket cover 4, and further, if the handrail post 2 is erected with the bracket body 3 fixed to it, it is possible to eliminate the need to work from the outside when fixing the bracket body 3, thereby improving work efficiency.

[Effect of the idea]

As is clear from the above explanation, according to the Kasagi bracket of the present invention, the outdoor side fixing is inserted and engaged in a pressure welding manner, and the indoor side is screwed at the same time as the engagement, so that the handrail bracket will last for a long time. Since it can be firmly fixed and the fixing work can be performed only from the indoor side, work efficiency can be improved and the safety of the fixing work can be increased.
