Abstract

Metal barriers in spare parts. The invention relates to a metal barrier which can be adapted to all height differences and to all angles between frames, it allows opening at the lowest cost. It consists of vertical posts (1) on which are welded connecting pieces (4) holding the frames (3) in the groove by bars (5) with the tamper-evident screw. For a fixed frame to become mobile, it suffices to add on one side a flat washer on the screw (6) between parts (4) and (5) in order to give play to the frame, and to replace on the opposite side of the frame the bar (5) by the bar (7) with its screw (10) and its spring (11). This bar, by pivoting a quarter of a turn, frees the frame, which becomes a gate.

Description

--1 -

  The present invention relates to the improvement

metal barriers.

  The term "barrier" is taken here in its widest sense and refers to exterior barriers intended to delimit a property, guardrails for terraces, balconies, or for

stairs, with a handrail.

  A barrier generally comprises vertically arranged metal poles on which are fixed various screens, stiffened by added reinforcements, affecting various shapes and connecting two posts made integral by various means such as welding, fitting, ligating etc ... and which have, in in addition, for the purpose of receiving a grid constituting

fence.

  In other cases the metal barriers are

  fully welded, made to measure.

  Currently, a portion of damaged metal fence requires to resume all or substantially

fence.

  The present invention has the effect of avoiding all these drawbacks, both at the industrial level concerning the manufacture, and at the practical level of setting up or

  possible repairs, even modifications.

  According to the invention, all the reinforcements are removed, as much on the poles as those used for

fixing the screens.

  The implementation of the invention does not require any particular qualification, any more than any tooling, if not a key for the screws.

with tamper evident head.

  In addition, it is common in addition to a specific repair of the barrier, that we need to preserve a passage, without breaking the harmony in the continuity of the barrier, other than that originally planned for doors and gates. Example: in low barrier, installed around a lawn, it is essential to leave the passage to a mower, or in another case to provide a place of occasional passage in the barrier to allow the passage of a big machine having to intervene in the property. In the case of very occasional openings, dismantling the panels, or even a post, will suffice without

  that the barrier is of any kind damaged.

  In the case of a passage a little more frequent, the replacement of the closing bar on the connecting piece by a bar comprising a spring, allowing the maintenance in the closed position and can also rotate a quarter turn to release the

  frame that can then move as a portal.

  The present invention meets all these needs.

  The various features and benefits of

  the invention will emerge from the description which will

  to follow, being well specified that all other forms, proportions and arrangements could be

  adopted without departing from the scope of the invention.

  In the course of this description, reference is made to

  schematic drawings attached which show: Figure 1 view of a metal barrier placed on a horizontal ground; Figure 2 exploded perspective view of the assembly between a pole and two frames; Figure 3 cross-sectional view of the barrier of Figure 2 in the assembled position; Figure 4 view of a metal barrier placed on uneven ground; Figure 5 top view of a barrier to be installed at different angles; Figure 6 exploded perspective view of a fixed link piece; Figure 7 exploded perspective view of a connecting piece offering the mobility of the

frame.

  The barrier according to the invention comprises a number of vertical posts (1) and (2) on which are welded connecting pieces (4), for receiving frames (3) in the groove, (13) maintained by clamping with a closing bar (5) and

a tamper-evident screw (6).

  According to a preferred embodiment of the invention the frames (3) are made of round iron, of standardized dimensions both in the heights and in the lengths in order to allow the barrier to marry at best the different geometric shapes desired, as much as possible. vertical according to the unevenness fig. 1 and fig.4 that horizontal fig. 5, allowing a

  orientation of the executives practically 360.

  The continuity posts (1) are equipped with - 4 - connecting pieces (4) on both sides, while the

  end posts (2) have only one side.

  Fixing these poles can be done by: - sealing tabs, in this case the post is open to the foot a few centimeters and then flared so

  to lodge directly in a concrete massif.

  - welded plate, allowing fixation on rods

anchored filaments.

  - sleeve, a sealed sheath receiving the pole, keeping to this one the advantage of being

removable.

  Thanks to the provisions adopted according to the invention of the barrier at 11, the industrialization as well as the assembly and the repair are advantageously simplified. Figure 2 shows a barrier in progress

setting up.

  In the case of a mobile frame, simply add a simple flat washer on the screw (6) between the pieces (4) and (5) to give the frame (3) ease in the groove (13). ) allowing it to pivot and replace on the opposite side of the frame the workpiece (5) and the screw (6) by the closing piece (7) provided with a shoulder hole (12) for receiving a spring (11)

mounted on the screw (10).

  The spring (11) holds the piece (7) in the closed position while allowing it to rotate a quarter of a turn to release the frame that has been

desired mobile.

  In the variant presented, it is the horizontal wire of the welded mesh which keeps the frame in the throat

  (13) during its pivoting. All other forms of filling can be chosen to meet this

  function without departing from the scope of this invention.

  These occasional openings are virtually invisible throughout the barrier and offer a very economical solution to the problem.

cost of a portal.

  As is apparent from the foregoing, the invention provides a great improvement to the existing technique by providing a metal barrier of simple structure, which can be installed by unqualified people, while being a very pleasant aesthetic, since giving the impression of a custom-made, fixed barrier without presenting the

disadvantages of this technique.

  On the other hand the possibility of occasional opening of this barrier replaces advantageously

  in all respects what exists today.

  Of course, the invention is not limited to the embodiments of this barrier described above as an example; she kisses, at

  contrary, all the variants.

  This is how the shape and nature of the parts could be different without

  so far from the scope of the invention.

Claims (4)

claims-   1 - Metal barrier in parts, of the type comprising vertical poles (1) and (2), on which are fixed frames (3) filled with wire mesh or any other form of filling, characterized in that the fasteners of these frames on the poles are effected by a part integral with the post having a groove (13) for receiving the frame, the latter being held by means of a head screw   tamperproof (6) tightening a closing bar (5).   2 - metal barrier according to claim 1 characterized in that, in the case of an intermediate pole (1), the connecting pieces are of on both sides of the pole.   3 - Metal barrier according to the claims   preceding, characterized in that, in the case of an end pole (2), the connecting pieces are not find that on one side of the pole.   4 - Metal barrier, according to any of the   preceding claims, characterized in that, the   connecting pieces (4) have a groove (13) for receiving the frames allowing an orientation thereof practically 360.   - Metal barrier, according to any of the   preceding claims, characterized in that, the   frames being connected to the posts by clamping can be adjusted to the desired height, thus meeting all desired height differences.   -7- 6 - Metal barrier, according to any of the   preceding claims, characterized in that, the   Poles and frames being of standard dimensions can be replaced without touching the rest of the fence. 7 - Metal barrier, according to any of the   preceding claims, characterized in that, the   frames can be made movable by simply adding a flat washer between the connecting pieces (4) and (5) on one side thus providing the necessary clearance in the groove (13), and on the opposite side by the replacement of the clamping bar (5) by the bar (7) comprising a spring (12) for pivoting a quarter of a turn thereof in order to free the frame.
