Description

[Detailed description of the invention] The purpose of this invention is to securely fix the support and the cap and close the upper end of the support in a liquid-tight manner, as well as to facilitate the manufacture of the parts used and improve the workability of fixing. This invention relates to a fixing device for a handrail with a cap and a post.

Conventionally, in order to fix the support of a handrail (including a fence or fence, etc.; the same shall apply hereinafter) and the cap, the structure is generally such that the bottom surface of the cap is fixed with screws to a bracket fixed to the upper end side wall of the support with bolts. However, with this structure, the lateral force applied to the cap is not only applied directly to the screws, which is undesirable, but also allows rainwater to easily enter the inside of the support, and because the bracket is exposed, it spoils the aesthetics. There were problems such as poor workability.

Therefore, a structure was proposed in which a hole was formed in the lower surface of the Kasagi to pass through the upper end of the column so that the column head would protrude slightly upwards, but this did not improve the former in terms of workability and appearance.

In addition, a device has been proposed in which the vertical part of the L-shaped bracket is inserted into the column and the horizontal part is inserted into the cap. No consideration was given to stopping them, and they were not perfect in preventing rainwater from entering the pillars.

In this invention, the cap is divided into upper and lower parts, a bracket is inserted and fixed into the cap and is inserted into the upper end of the support, and a lid covering the end of the support is fixed to the support from above the bracket. The horizontal lower surface of the bracket is provided with a groove into which the upper end edge of the column fits, and the lid is shaped to cover the upper end opening of the column, and the lower surface is provided with a recess that engages with the protrusion or groove on the upper surface of the bracket. Grooves or ridges are provided to prevent rainwater from entering through the column openings.

In addition, a protrusion for attaching a bracket is provided on the inside of the column to enable temporary attachment of the bracket, thereby improving workability. Furthermore, a groove is provided on the upper surface of the horizontal portion of the bracket for fixing it to the lower part of the cap to prevent the cap from shifting in the lateral direction.

In addition, the bracket and lid can be hooked by providing protrusions or grooves in the same direction only, so if you cut the extruded material to the specified size, you can use it as is. , there was no need to drill fixing holes in the pillars, and workability was significantly improved.

An embodiment of this invention shown in the drawings will be described below.

Kasagi 2 to the left and right side walls of the upper end of the pillar 1, which has a square cross section.
A bracket 4, which has a round-shaped cross section, is arranged so that the end surfaces of the lower members 3, 3 are in contact with each other, and
4, and the bottom plates 3a, 3a and horizontal protrusions 3b, 3 of the lower members 3, 3.
Insert the horizontal parts 4a, 4a of the brackets 4, 4 between the brackets 4, 4, and fix them into the grooves 4b, 4b provided on the upper surface of the horizontal parts of the brackets 4, 4 with screws 5 passing through the protrusions 3b, 3b, or The protrusions 3b, 3b are grooved 4
Crimp it inside b and 4b to fix both.

Inside the opening of the support column 1, a pair of left and right protrusions 1a, 1a are installed vertically at a predetermined distance from the outer wall (corresponding to the thickness of the vertical parts 4c, 4c of the brackets 4, 4). Therefore, by inserting the vertical portion 4c of the bracket 4 under pressure, both can be firmly temporarily fastened. Incidentally, an uneven strip 4 is formed on the side wall of the vertical portion 4c.
If d is provided, friction during insertion can be made even more effective.

A vertical portion 4 is provided on the horizontal lower surface of the bracket 4.
A protrusion 4e is provided at a predetermined distance (corresponding to the thickness of the column) from the base of the column c, and one side wall of the upper end of the column is in a groove 4f formed by the vertical portion 4c and the protrusion 4e. It is designed to be inserted. In the above, the lower surface of the bracket 4 is the bottom surface 3 of the lower member 3.
a, so the end of the support is in the groove 4.
The depth f is maintained higher than the bottom surface of the lower member 3, thereby preventing moisture on the bottom surface 3a of the lower member from entering into the support column.

A cover 7 of the support post is placed over the brackets 4, 4, and the cover 7 is fixed to the support support with screws 8. The lower surface of the lid 7 is brought into close contact with the end surface of the support column 1, and the grooves 7a, 7a provided on both sides of the lower surface of the lid 7 are fitted into and latched onto protrusions 4g, 4g provided on the horizontal upper surfaces of the brackets 4, 4. In this case, if a packing 9 is provided on the lower surface of the lid 7, the sealing performance is further improved. Therefore, the column 1 and the bracket 4 are reliably connected by the lid 7, and furthermore, the column and the lower member 3 of the cap 2 are securely connected via the bracket 4.

Once the upper member 10 is fitted as described above and the hanging grooves 3c provided on the front and rear sides of the lower member 3 are hooked onto the hanging strips 10a provided on the lower edges of the front and rear inner walls of the upper member 10, the handrail made using the device of this invention is completed.

That is, according to this invention, a bracket and a lid are interposed between the support and the cap, and the bracket and the bracket with one end inserted and hooked to the cap, the bracket and the support with one end inserted, and the cover and the bracket hooked to each other. Since the three parts of the structure and the pillar are integrally fixed, the connection between them is solid and reliable.

In particular, since the groove on the lower surface of the bracket is fitted into the edge of the column opening, and the lower surface of the lid is fitted with the upper surface of the bracket, it is possible to reliably prevent rainwater from entering through the column opening. Furthermore, since a protrusion for clamping the bracket is provided on the inside of the column, the bracket can be temporarily fixed, improving work efficiency.

Furthermore, since the upper surface of the bracket is provided with a groove for fixing it to the lower part of the cap, it is possible to prevent the cap from shifting in the lateral direction.

Furthermore, since the bracket and the lid are formed with protrusions or grooves in the same direction, they can be completed by simply cutting the extruded material, and are relatively inexpensive and easy to manufacture. Furthermore, since both the bracket and the lid are covered with Kasagi, there is no risk of spoiling the aesthetic appearance.
