Description

[Detailed Description of the Invention] The present invention relates to an improvement in the mounting structure of a horizontal member such as a stand support in a handrail structure, in which the horizontal member is attached to a column in a butt state.

Conventionally, various types of mounting structures have been proposed.

For example, as a representative example, US Patent No. 349858
There is one disclosed in Specification No. 9.

In this invention, the stand support, which is a horizontal member, is attached to the column via the mounting bracket.In this case, the stand support is fitted from above to the mounting bracket attached to the support, and then the stand support that is installed on the stand A wedge is driven into the groove between the protruding piece and the mounting bracket to secure the stand support to the post.

However, in the above-mentioned method, the wedges must be driven from below on the stand supports, resulting in poor workability, and the wedges are often not driven straight, so there is a risk that they may fall off during handrail assembly or due to subsequent vibrations, etc. There were some drawbacks.

The present invention has been made in order to eliminate the above-mentioned conventional drawbacks, and includes attaching fixing tools and crimping tools that constitute a mounting bracket to the main body of the horizontal member via protrusions provided on the main body of the horizontal member. By screwing the mounting screw from the mounting bracket to the column, the fixing device can clamp the protrusion and at the same time fix it to the column.The installation work is easy, and since it is fixed with screws, the mounting bracket will not be damaged by vibration etc. The purpose of the present invention is to provide a mounting structure for horizontal members that will not fall off.

Next, the present invention will be explained with reference to the drawings, which are one embodiment.

FIG. 1 is a front view of a balcony handrail to which the horizontal member mounting structure according to the present invention is applied, in which 10 is a column, and 20 is a horizontal frame attached below the column 10 via a mounting bracket 30 (not shown). The stand holder 50 is a stand provided on the stand holder 20, and 60 is a cap that is attached to the top of the stand 50 and the upper end of the support 10 via connecting fittings (not shown).

Each member thereof is as shown in FIG.

That is, the support column 10 is made of an extruded aluminum material with a square cross section, and has screw mounting seats 11 on the inner side of each side, and holes 12 are provided at predetermined positions below.

The stand support 20, which is a horizontal member, is made of extruded aluminum and consists of a main body 21 and a cap 25, and the side wall 22 of the main body 21 of the stand support has a pair of opposing first protrusions 23. Further, a second claw protrusion 24 is provided below it.

On the other hand, the cap 25 is provided with a protrusion 26 that press-fits with the second claw protrusion 24.

Reference numeral 30 denotes a mounting bracket, and a fixture 31. It consists of a crimping tool 39 and a mounting screw 44.

The fixture 31 has parallel first and second projecting pieces 32.3.
5 and the base 36 form a substantially U-shape, and the first projecting piece 32
A groove 33 is provided in the groove 33 .

Further, the base 36 is provided with a screw hole 37 that communicates with the space 34 formed between the protrusions 32 and 35, and furthermore, the base 36
On both sides of 6, the vertical support is provided with grooves 38 which are inserted into and fit into the first claw protrusions 23 of the main body 21.

On the other hand, the crimping tool 39 consists of opposing long and short protrusions 40 and 41 that are substantially in the same direction as the concave groove 33 of the fixing tool 31, and a base 42. The base 42 is provided with a screw hole 43, and has long and short protrusions. The spacing between the pieces 40, 41 widens toward the tip.

Next, a method for attaching the stand support 20 having the above structure to the support column 10 via the attachment fittings 30 will be explained.

First, the struts 10 are mounted vertically at predetermined intervals using a conventionally known method.

Next, the stand supports cut to the spacing of the pillars 10 are attached to the ends of the main body 21, and the long protruding pieces 40 of the crimping tools 39 are inserted into the grooves 33.
Loosely fit the short protruding piece 41 into the fixture 31 so that it is positioned on the lower surface of the second protruding piece 35, and insert the mounting screw through the groove 38 with the mounting screw inserted into the screw hole 37.43. .

Then, when the mounting screw is screwed into the hole 12 of the pillar 10,
By tightening, the crimping tool 39 is guided by the concave groove 33 and advances straight, and the thin-walled fixing tool 31 is moved forward by the short projecting piece 4.
The second protruding piece 35 is displaced inward, that is, the first claw protruding strip 23 is clamped by the first and second protruding pieces 32 and 35, and at the same time the fixture 31 is firmly attached to the support column 10. It will be done.

Thereafter, by pressing the cap 25 against the main body 21 from below, the stand support 20 is integrated and the assembly is completed.

The shapes of the fixing tool 31 and the crimping tool 39 are not limited to those in the embodiment, and the first claw protrusion 23 of the main body 21 of the stand support is clamped by the first and second protruding pieces 32,35 of the fixing tool 31. Therefore, the first and second projecting pieces 32 and 35, and the projecting piece 40 of the crimping tool 39
, 41 may be fork-shaped, and the pawl protrusion 23 may be a mere protrusion.

In addition, although the above explanation described the case where only the stand holder 20 is attached to the support 10, the stand 50 and the Kasagi 6 are attached to the support 10.
0, the main body 21 is attached to the lower end of the stand 50 via a screw seat, and the Kasagi support 6 described below is attached to the upper end.
1 with screws not shown.

The Kasagi receiver 61 and the Kasagi main body 65 constitute the Kasagi 60, and the lower surface of the Kasagi receiver 61 has a concave groove 62 in which the stand 50 is placed, and the upper surface has a pair of first protrusions 63, 63. It is provided with second claw protrusions 64, 64 on the outside.

On the other hand, the Kasagi main body 65 has the second claw protrusion 6 on the inner side wall thereof.
4 and 64, and a claw protrusion 66 that fits with the claws 4 and 64.

The Kasagi receiver 61.61 attached to the stand 50 has a projecting piece 71.61 of the connecting fitting 70 at its end. The first claw protrusion of the sword 63
, 63, and the bifurcated leg portion 72 of the connecting fitting 70 is inserted into the support column 10 using the screw mounting seat 11 as a guide.

Next, screw the screw 74 into the groove 73 with a part of the head 75.
By locating the caps inside, the Kasagi supports 61 are connected to each other and supported by the pillars 10.

After that, the stand 50 is attached, and the mounting screw 44 of the mounting bracket 30 fitted into the stand support 21 is tightened as described above to fix the stand support 21 to the support 10.

Then, the cap 25 and the cap 65 are fitted together by pressing the stand support from below the main body 21 and from above the cap 61 to form a balcony handrail.

The stand 50, the cap 60, and the connecting fittings 70 are all made of extruded aluminum.

Further, the above-mentioned cap 60 and stand guard 20 are attached to the corner pillars by a conventionally known method.

As is clear from the above description, according to the present invention, the horizontal members that are butt-attached to the columns are attached using mounting brackets, as in the past, but the crimping tool that produces the wedge effect is mounted using mounting screws. It is reliable because it is attached to a fixture, and at the same time, it is easy to work because it can be attached to the horizontal member and the support column in one operation via the fixture.

In addition, it goes without saying that the horizontal member to which the present invention is applied is not limited to the stand support.
