Description

GUARD RAIL CONSISTING OF A SET OF SPARE PARTS READY TO BE ASSEMBLED.

Description

Technical Field of the Invention The subject of the invention is a railing consisting of a set of spare parts ready to be assembled.

It concerns the technical field of railings and more particularly that of railings to assemble.

State of the art

Railings consist of a set of spare parts ready to be assembled. These railings are generally formed by the assembly of uprights and sleepers formed by aluminum profiles.

However, the profiles used have profiles whose complex shape is difficult and expensive to manufacture. In addition, the assembly time of these railings is particularly long, firstly due to a large number of parts to be assembled, and secondly due to a problem of identification and distinction among the profiles of those forming the sleepers and those forming the uprights, the set of profiles having, for aesthetic reasons, similar shapes that can be easily confused.

In view of this state of affairs, the main purpose of the invention is to provide a light railing consisting of a minimum of spare parts quickly. identifiable, said parts can be easily and quickly mounted and taking up a minimum of space during transport.

Another object of the invention is to provide a guard rail of simple and inexpensive design.

Disclosure of the invention. The solution proposed by the invention is a railing consisting of a reduced set of spare parts ready to be assembled. This railing is remarkable in that it comprises as spare parts:

at least two uprights each formed of a vertical flat blade having at least one hole,

- for each amount, a plate on which said amount is intended to be fixed,

at least one transverse element intended to be positioned transversely to the uprights, said transverse element being intended to be inserted into the bores of said uprights, said transverse element and said bores having a complementary shape,

for each transverse element, at least one temporary fixing means arranged on the edge of each upright and intended to apply a contact force directly on the transverse element so as to constrain the latter against the inner wall of the bore and ensure its maintenance. position on said amount.

Such a railing has few parts assembling easily and quickly by interlocking. In addition, the amounts formed of a flat blade are easily identifiable among the other parts, which can significantly reduce the assembly time.

The temporary fixing means is advantageously in the form of a set screw intended to be screwed into a threaded hole made on the portion of the uprights, said tapped hole opening into the bore, the end of said needle screw being intended to exert a contact force directly on the transverse element so as to constrain the latter against the inner wall of the bore and ensure its maintenance in position on said amount. The needle screw makes it easy and quick to hold the transverse element in position on the uprights, said needle screw cooperating with a threaded hole made on the upright resulting from a simple, fast and inexpensive machining. According to a particular embodiment of the invention, the railing comprises:

at least two transverse elements: an upper transverse element and a lower transverse element, each transverse element being intended to be inserted into upper and lower bores made in the uprights, said transverse elements and said bores having a complementary shape,

at least one plate intended to fit against or around or between the upper and lower transverse elements according to the chosen model,

It is thus possible to manufacture a railing equipped with a plate using a minimum of parts, the latter being quickly and easily assembled to each other.

According to an advantageous characteristic of this particular embodiment, the plate is made of glass, joints being intended to be arranged between the plate and the upper transverse element and / or the lower transverse element so as to call said plate between said elements. transverse. The glass plate is thus clamped between the transverse elements by means of joints so that it does not break. To easily and simply fit the amounts on the plates, the latter advantageously have a slot in which is intended to engage the lower part of the amounts. To securely fix the plates against the ground, said plates preferably have oblong holes for the passage of fixing means for the plating of said plates on the ground, said plates being movable relative to said fixing means via the oblong holes, in a sliding motion on the floor.

To immobilize the plates at the end of the assembly of the railing, said plates may have at least one threaded hole in which a set screw is intended to be screwed, the end of said set screw being intended to exert a contact force against the ground so as to oppose the sliding of said plate on said floor and to compensate for possible planimetry defects of the generally masonry ground. To obtain guardrails sufficiently secure according to the standards in force, the guardrail can include as spare parts several transverse elements intended to be positioned transversally to the uprights at different heights, each transverse element being intended to be inserted in bores. made on said uprights, said transverse elements and said holes having a complementary shape.

The transverse element intended to be arranged highest on the uprights is preferably a tube having a diameter of at least 50 mm and a thickness of at least 2 mm. The transverse element thus formed has sufficient strength to meet the safety standards in force.

The transverse element or elements intended to be arranged below the uppermost transverse element are advantageously tubes having a diameter at least equal to 20 mm and a thickness at least equal to 1.5 mm. The lower transverse elements then have sufficient strength to meet the safety standards in force. Description of the figures.

Referring to Figures 1.a) to 1.c), the guardrail (1) comprises at least two uprights (2) at each of its ends, one or more other uprights (2) can be interposed between. These amounts (2) may or may not be spaced regularly. In practice, the railing (1) has an amount (2) every 150 cm, but may also include an amount (2) every 80 cm, every 100 cm, every 180 cm, every 190 cm, etc. As shown in Figs. 2 (a) to 6 (c), a post (2) consists of a vertical flat blade. The term "blade" means a flat elongated strip longer than wide, and possibly wider than thick. The uprights (2) are made of a hard material such as metal, wood, composite material, etc. Preferably and in order to lighten the guardrail (1), the uprights (2) are made of light material of the aluminum or aluminum alloy type. They can be obtained by machining, molding, rolling, cutting, etc. The uprights (2) may have a thickness ranging from 1 cm to 3 cm, a width ranging from 5 cm to 10 cm and a length ranging from 20 cm to 120 cm. The corners and edges of the blade can be chamfered or rounded.
