Description

[Detailed Description of the Invention] The present invention relates to an improvement in the mounting structure of a horizontal member such as a handrail, which is attached in a T-shape to the upper end of a column having a square cross section.

Conventionally, various types of mounting structures have been proposed.

For example, as a representative example, JP-A-50-205
There is one disclosed in Publication No. 25.

In this invention, especially the one shown in Fig. 8, the connecting fitting inserted into the column is driven in, the both sides are expanded outward, the connecting fitting is attached to the column as if driving a wedge, and then the connecting fitting is attached to the column by tapping. After both are securely fixed with screws, a handrail or the like is attached to the column in a T-shape via the connecting fittings.

However, according to the above-mentioned method, it is troublesome to drive the connecting fitting into the support, and since the tapping screw mounting seats are provided only on the inside of the two opposing sides of the support, it is inevitable that the connection fittings must be driven into the support. The direction of the mounting piece is restricted to one direction, and the direction must be taken into consideration when installing the support, which has the disadvantage of poor workability.

The present invention has been made to eliminate the above-mentioned drawbacks of the conventional method.If the connecting fitting is provided with a leg piece and inserted so as to be in contact with the inner wall of the column, the column can be secured without shaking even if it does not expand inward. Taking into consideration the fact that the connecting fitting can be positioned inside the supporting column, and that if the upper surface of the connecting fitting is crimped to the column with screws, the connecting fitting can be reliably attached to the column in exactly the same way as in the conventional example, To provide a mounting structure for a horizontal member, in which the cross section is square and screw mounting seats are provided on each side, so that columns can be mounted without driving any connecting fittings and without considering directionality. The purpose is to

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, where 10 is a column, and 30 is a horizontal member attached to the upper end of the column 10 via a connecting fitting (not shown). In a certain Kasagi, 40 is a standing child support, and 70 is a standing child installed between the Kasagi 30 and the standing child support 40.

Each member is as shown in FIG.

That is, the pillar 10 is made of an extruded aluminum material with a square cross section, and screw mounting seats 11 are provided on the inner side of each side to which mounting screws 38 described below are screwed.

The connecting fitting 20 is also made of extruded aluminum, and has leg pieces 21, 21 which are fork-shaped downward, and mounting pieces 24 which extend upward on both sides. 24, and a mounting piece 24.24 on the center upper surface.
It has a recess 25 perpendicular to the protruding direction of 24.

The width l1 of the leg piece 21 and the mounting piece 24 is approximately the same as the distance l between the opposing screw mounting seats 11 and 11, and the width l1 of the leg piece 21 and the mounting piece 24 is approximately the same as the distance l between the opposing screw mounting seats 11 and 11, and the bulge portion provided on the outside of the leg piece 21, 21 is 22,
22, and the distance l2 between the base step portions 23, 23 is also approximately the same as l.

The kasagi 30, which is a horizontal member, consists of a kasagi main body 31 made of extruded aluminum and a kasagi receiver 34. The kasagi receiver 34 has a concave groove 35 on the bottom surface for positioning the stand 70, and a top surface for the connection fittings 20. The opposing first claw protrusions 36 and 36, which are attached by sliding the mounting piece 24, are fitted from above with the claw protrusions 33 provided on the side wall 32 of the cap body 31 on the outside thereof, to attach the cap body 31. It has a second claw protrusion 37 that prevents it from coming off and is integrated with it.

Next, a method of attaching the cap 30 made of the above-mentioned structure to the support 10 via the connecting fitting 20 will be explained.

First, the columns 10 are mounted upright on the floor at predetermined intervals using a conventionally known method.

Next, the connection fittings 20 are attached to the ends of the Kasagi receivers 34 cut at intervals of the columns 10 by inserting the attachment pieces 24 between the first claw protrusions 36, 36, respectively.

Thereafter, the leg piece 21 of the sustaining metal fitting 20 is inserted into the support column 10.

In this case, the bulging portion 22 and base stepped portion 23 of the leg piece 21 as well as the side wall 26 of the leg piece 21 are each guided between the screw mounting seats 11, and the connecting fitting 20 is inserted into the support column 10.

Next, the screw 38 is screwed into the screw mounting seat 11 that is not covered by the mounting piece 24, and a part of the head 39 of the screw 38 is inserted into the recess 25.
The connecting fitting 20 is screwed in such a way that it is positioned inward to prevent the connecting fitting 20 from coming off from the support column 10.

When the Kasagi receiver 34 is attached to the support post 10 as described above, when the Kasagi main body 31 is pressed onto the Kasagi receiver 34 from above,
The side wall 32 expands slightly outward, and its pawl protrusion 33 engages and integrates with the second pawl protrusion 37 to complete the installation.

In addition, although the above explanation was about the case where only the cap 30 is attached to the support 10, in order to attach both the stand holder 40 and the stand 70 to the support 10, it is necessary to attach the above-mentioned cap holder 34 and stand support main body 41 to the upper and lower ends of the stand 70. Screw (not shown)
At the same time, the stand receiving fittings 50 are attached to both ends of the stand receiving main body 41. 56 loosely.

In this case, the long piece 57 of the fitting 56 is located in the upper recess 51 of the fitting 50, and the short piece 58 is located on the lower surface of the thin piece 53 provided through the cavity 52 of the fitting 50.

Further, the upper surface of the short piece 58 is provided with an inclined surface 59 that becomes thinner toward the tip.

In the mounting bracket 50, a groove 55 provided in the hollow space 52 and a base portion 54 connected thereto is fitted into the claw protrusion 42 provided on the inner surface of the stand support main body 41.

Next, as described above, the Kasagi receiver 34 is attached to the support post 10 via the connecting fitting 20, and screws are inserted through the hole 60 provided in the mounting fitting 56 and the hole (not shown) provided in the base 54 of the fitting 50 connected thereto. 61 and screwed into the screw hole 12 provided in the support column 10.

In this case, as the screws 61 are screwed together, the mounting bracket 56 moves forward, and the inclined surface 59 provided on the short piece 58 causes the thin piece 53 to
The tip part bends upward and engages the claw protrusion 42 of the stand guard main body 41.
can be securely attached to the support 10.

Thereafter, the claw protrusions 45 of the stand support cap 44 are fitted to the claw protrusions 43 of the stand support body 41, and the cap body 31 is fitted and attached to the cap support 34 as described above.

The stand supports 40 and the stand 70 are made of extruded aluminum.

Note that the method for attaching the stand support 40 itself to the support column 10 is not limited to the above-mentioned method, and may be any conventionally known method.In addition, the attachment of the Kasagi support 34 to the corner post is performed by attaching the Kasagi support 34 to the corner post from the end to the first claw protrusion. One side of the L-shaped metal fitting may be inserted between the strips 36, and the other piece of this metal fitting may be attached to the corner post with screws.

Furthermore, it goes without saying that the horizontal members are not limited to only Kasagi.

As is clear from the above description, according to the present invention, the T-shaped horizontal member attached to the upper end of the column is attached via a connecting fitting as in the conventional case, but this connecting fitting is not driven into the column in any way. It is extremely easy to install, as the legs are inserted into the column without any wobbling, and the screw head screwed onto the column prevents it from coming off. Since the connecting fittings are provided on the inside side, they can be installed from any direction. In other words, there is no need to confirm the installation position of the pillars each time depending on the installation direction of the horizontal members, which improves the workability of installing the pillars. It has advantages such as being able to
