Universal handrail and fences

Abstract

 System to join stretches of tube (10) which allows the construction of handrails and fences adaptable to any unevenness of the ground. It consists of:
One base plate (9) to fix the vertical support to the ground. One piece (7) to join the vertical support to this base (9) which allows a movement up to 180º . A third piece set into the upper end of the first stretch of the support with a screw threaded stud (2), which adapts to a fourth piece (3) set into the upper stretch, and which allows to fix a fifth piece consisting of a bush (5), a pin (6) and another piece (4) to fix another support. This piece allows a movement in the horizontal plane of 180º and in the vertical plane of 90º . This knot can be repeated as many times as necessary.
The upper piece (1) of the support is an hemisphere with a female screw to be adapted to a piece "three" (2).

Description

OBJECT OF THE INVENTION

[0001] The present invention refers to a new system to join stretches of tube, which allows the construction of handrails and fences adaptable to any unevenness of the ground without welding and with the possibility of recovering the pieces once they have fulfilled their function.

BACKGROUND OF THE INVENTION

[0002] Before the invention of this system, the handrails had to be built with several points of welding, moreover it was necessary to study the unevenness of the ground and too many stretches of tube were needed, which required a greater amount of labour and skilled workers.

DESCRIPTION OF THE INVENTION

[0003] This invention refers to a system of pieces pressed into the tubes and screwed to one another, which can be put in any position, both vertically and horizontally.

[0004] The vertical supports consist of one hemipherical cup (1) at the top with a female screw in the inferior part.

[0005] Piece 2 is a bush set into the stanchion with a screw threaded stud where pieces 1 and 2 can be adapted.

[0006] Piece 3 is set into the tube or stanchion 10 and has a female screw where another piece 2 is screwed.

[0007] One or more pieces 5 are trapped between these two; these pieces 5 allow the rotation in one plane, and joined to piece 4 by one pin 6, this piece 4 can be folded if required by the unevenness of the ground.

[0008] Knots 4, 5 and 6 between 2 and 3 can be repeated in the stanchion as many times as necessary.

[0009] Piece 7 is also a bush set into the tube 10 with two inferior laps which fasten the stanchion to piece 9 by means of a pin or screw 8.

[0010] Piece 9 or base of the stanchion is fixed to the ground with several screws.

[0011] The union of pieces 9 and 7 by means of a pin of screw 8 allows a movement up to 180 º.

DESCRIPTION OF THE DRAWINGS

[0012] This system is divided into three different figures (Fig. 1, Fig. 2, and Fig. 3) with several pieces repeated in each of them.

Figure 1 - It consists of two pieces 1 and 2 which offer the possibility to trap pieces 5 and 4 if it were necessary to build a handrail.

Figure 2 - This set 2, 3, 4, 5 and 6 will be repeated as many times as necessary, and at the height required by the fence or handrail.

Figure 3 - Two pieces joined by a pin or screw 8 which fixes the stanchion to the ground and allows to adapt it to any unevenness of the ground.

Claims

1. Handrail and fence consiting of a system of pieces set into the tubes and screwed to one another, which can be put in any position, both vertically and horizontally.

2. Handrail and fence, according to the previous claim, in which the vertical supports have at the top a hemipherical cup with a female screw in the inferior part (1).

3. Handrail and fence, according to previous claims, with a bush 2 set into the stanchion and with a screw threaded stud to adapt piece 1.

4. Handrail and fence, according to previous claims, with a bush 3 with a female screw to adapt piece 2.

5. Handrail and fence, according to previous claims, is a set 4, 5, and 6 which offers the possibility to rotate around the stud of piece 2 and to fold piece 4 by means of a pin 6, fastened to piece 5.

6. Handrail and fence, according to previous claims, with a bush 7 set into the lower part of the stanchion with two perforated laps to trap piece 9 or base of the stanchion.
These two pieces joined by a screw or pin 8 will keep the support in vertical position even if the ground is uneven.
