Description

The invention relates to the technical sector of guardrails installed in particular along motor vehicle traffic lanes.

More particularly, the invention relates to metal safety rails whose cross sectional profile is determined to provide sufficient strength to ensure the retention of vehicles. The sectional profile of these slides is well known to a person skilled in the art.

Generally, a slide is composed of at least one rail attached to support posts in combination with spacers.

More particularly, the problem to be solved by the invention is to temporarily interrupt the continuity of the assembled smooth rails, to create an opening for the passage, for example, of a safety or maintenance vehicle.

Various technical solutions have been proposed to develop such openings. In this regard, one distinguishes essentially either a solution for mounting and fixing removably at least one smooth relative to other smooth which become fixed, or a solution for making mobile at least one smooth relative to other smooth which remain fixed.

The invention relates more particularly to the movable assembly of a smooth relative to the others which remain fixed.

Advantageously, the invention proposes a solution according to which at least one rail is mounted with guided linear sliding capacity relative to the other rails which remain fixed. This state of the art can be illustrated by the teaching of FR 2,795,439 which the applicant of this is also the holder.

Essentially, this patent relates to an opening device for a sliding type of metal safety slide and comprising at least one slide member movable in translation of a length greater than the length of the opening to be created by displacement of said element. slide. The upper part of the movable slide element has a longitudinal profile forming a guide rail for its displacement in translation. This longitudinal profile cooperates in support with rollers or pulleys carried by fixed slide elements adjacent to the opening. The rollers or pulleys are movable transversely on their axis of rotation, so as to allow laterally offset the sliding slide member to prevent the latter from rubbing on the adjacent slide elements fixed during its sliding.

However, it appears difficult to mount to allow the movable mounting of rollers or pulleys. The result obtained is not satisfactory. It is also observed that the length of the opening that can be created is limited (generally 4 meters).

The object of the invention is to remedy these disadvantages in a simple, safe, effective and rational manner.

From this state of the art, the problem to be solved by the invention is to ensure the free sliding of at least one movable bar with linear sliding capability without friction and in a perfectly guided manner. Another problem to be solved by the invention is to simplify and improve the sliding assembly of the movable boom.

To solve such problems, it has been designed and developed a sliding mounting device of at least one safety rail, said device which comprises support assemblies on which are fixed the ends of the fixed rails located at each end the opening to be created, at least one of said sets being arranged for mounting at least one roller adapted to allow the sliding of the movable rail and for mounting a pivoting member adapted to cause the tilting of said movable smooth relative to said roller for contacting a guide member that has the movable rail with the fixed rails for its free sliding in a guided manner, and without contact as its linear movement.

To solve the problem of increasing the opening to be created, the device comprises at least one independent support assembly equipped with rolling members adapted to cooperate with a portion of the profile of the sliding slide when sliding, said assembly being disposed substantially in the middle part of the opening.

In order to solve the problem posed by the linear sliding of the movable beam, the various rolling members or rollers are fixed in translation and cooperate with a profiled edge that the edge presents. rectilinear upper movable slide, the axis of rotation of said members being perpendicular to the direction of movement of said movable slide. The profiled flange partially encloses the running gear.

To solve the problem posed to be able to move the movable boom, in order to avoid any contact with the fixed rails, as and when its linear movement, the pivoting member, for the tilting of the movable rail, is constituted by a bent lever mounted with hinge capacity in a support yoke that has the support assembly, the free end of said lever being equipped with a roller adapted to bear with a portion of the movable boom under a pivoting effect of said lever.

Advantageously, the lever cooperates with locking means in the tilted position of the movable boom.

In an advantageous embodiment, one of the support assemblies on which the end of the fixed hinges is fixed, has means in the form of a pivoting lever adapted to ensure the locking in the closed position of the movable boom.

According to the invention, each support assembly comprises a plate receiving the rolling members and allowing, for the assemblies located at each end of the opening, the assembly of assembly member for the fixing of the fixed rails, each plate being integral. a retractor adapted to be fixed on a pole.

In general, the invention applies to safety barriers for motor vehicles, of the type of those comprising at least one rail attached to support posts via spacers.

More particularly, the problem to be solved by the invention is to ensure the sliding assembly of at least one movable bar (1) to create an opening (2) relative to two smooth (3) and (4).

The invention finds an advantageous application for all metal smooth, perfectly known to those skilled in the art. For example, as shown in the figures of the drawings, these slats have a cross section delimiting a central core (A) with, on either side and in a symmetrical manner, a profile (B) forming a wave. Fixing the fixed rails relative to the support posts equipped with spacers is performed at the central core (A). The movable boom (1) is slidably mounted relative to the fixed rails (3) and / or (4), in combination with rolling members, in particular rollers (5).

According to the invention, the free ends of the fixed heddles (3) and (4) are respectively fixed on support assemblies (6) and (7).

At least one of the support assemblies (6) is arranged for mounting at least one rolling member (8) adapted to allow the sliding rail (1) to slide with the other rolling members (5) arranged at level of fixed healds (3) and / or (4). The support assembly (6) comprises a fixing plate (9) having arrangements for the passage of assembly members in particular, for attachment to the end of the fixed rail (3), at its central soul (A).

The running gear (8) is rotatably mounted to the upper part of the plate (9), partially projecting from the latter to allow, as indicated in the following description, the free sliding of the movable rail ( 1) in combination with the rolling members (5) (in the form of rollers for example). More particularly, the rectilinear upper flange (1a) of the movable slide (1) is supported, by its internal face, on the various rollers (8) and (5) constituting a rolling zone of said rollers.

The axis of rotation of the rollers (5) and (8) is perpendicular to the direction of movement of the movable slide (1), said axes and said rollers being fixed in translation. Note that the mounting of the roller (8) on the plate (9) can be realized in combination with an anti-lifting bracket (10).

The plate (9) is secured to a spacer member (11) having fastening arrangements on a support post (12) to allow mounting in alignment with other assemblies support and spacer, to which are coupled the fixed rails. For example, the spacer (11) has tabs (13) for the adjustable mounting relative to the support post (12).

According to another characteristic, the lower part of the plate (9), substantially at the level of the roller (8), has arrangements for mounting a pivoting member adapted to cause the tilting of the mobile rail (1) relative to the roller (8). In an important way, the tilting of the movable rail (1) is intended to bring into contact a guide member (14) that the mobile rail (1) has with the rails (3) and / or (4) for allowing, concomitantly, the free sliding, in a guided manner and without contact, of the movable arm (1), as and when its linear movement.

This tilting is obtained by a pivoting lever (15) mounted to free articulation in a support yoke (16) fixed to the base of the plate (9). The free end of the pivoting lever (11), opposite its maneuvering end (15a), receives free rotation, a roller (17) adapted to bear with the portion of the movable boom, under the effect pivoting said lever (15). The axis of rotation of the roller (17) is disposed in a plane perpendicular to that of the axis of rotation of the roller (8).

Under an angular pivoting effect of the lever (15) relative to the yoke (16), the roller (17) bears on the movable beam (1) and causes, as it is pivoted, the tilting of said smooth (1) relative to the roller (8) in particular. Note that the lever (15) cooperates with a locking means in the tilted position of the movable boom (1). This means of locking may be constituted by a pin cooperating with different holes formed in the thickness of the yoke (16).

The guide member (14) is constituted by a rotary roller mounted free to rotate on a support (30) fixed on the side of the inner face of the lower profile (B) of the movable slide (1).

Note that the support assembly (6), defined above, can be mounted on the end of one of the fixed rails (3) or (4) or at the end of each of said rails (3) and (4). In the event that the guide support assembly is fixed in particular at the end of the rail (3) for example (figures of the drawings), the end of the other rail (4) is fixed on a support assembly said end (18). As before, this support assembly (18) has a mounting plate (19) of the end of the rail (4). This plate (19) also has a spacer element (20) arranged to be fixed on a support pole, under the same conditions as the guide spacer (6). The base of the plate (19) is arranged to allow the pivotal mounting of a lever (21) having arrangements (21a) adapted to ensure the locking in the closed position of the movable rail relative to the rail (4) by example. The lever (21) can be mounted in a support clevis (22) fixed to the base of the plate (19).

According to another characteristic and to obtain an opening (2) greater than the length of a mobile rail (1), at least one other independent support (23) is arranged for example in the middle part of the opening (2) in alignment with the other support assemblies (6) and (18) in particular. This independent support assembly (23) is equipped with bearing (24) and (25) adapted to cooperate with a portion of the profile of the movable slide (1) during its sliding.

In the same way as the support assemblies (6) and (18), the assembly (23) comprises a mounting plate (26) where the upper part receives, with free rotation, rolling elements (rollers (24) and (25)). Note that the rollers (24) and (25) are offset in height to facilitate closing the device. The plate (26) receives a spacer element (27) intended to be fixed on a support pole.

According to another characteristic, the rollers (5) that have fixed heddles are mounted at the end of vertical legs (28) with fixing arrangements on the corresponding fixed rail, particularly at its central core (A).

Of course, the fixed healds (3) and (4) and the movable heddle (1) are of complementary profiles, that of the movable heddle (1) capping that of fixed healds (3) and (4) in particular. In a known manner, the movable rail (1) may have an operating element in the form, for example, of a handle (29), to facilitate its sliding.

The use of the device is particularly simple, safe and effective. In the closed position of the opening (2) by the movable rail (1), the guide roller (14) escapes the end of the corresponding fixed rail (3). In this position, the support roller (17) is retracted. The mobile boom (1) is locked in translation by the end (21a) of the lever (21) which cooperates with a stop (31) of said rail (1).

Prior to the sliding of the mobile arm (1) in order to give free access to the opening (2), it is necessary to pivot the lever (21) to release said arm (1) and to act, also pivoting on the lever (15) to cause the tilting of said movable boom (2). Indeed, as indicated, the pivoting of the lever (15) causes the support of the roller (17) on the movable rail (1) and, concomitantly, its tilting as the pivoting of said lever taking into account of its length suitably determined.

Under the combined effect of the tilting and the linear displacement of the movable beam, the guide roller (14) bears on the external profile of the fixed beam (3) making it possible to significantly improve the sliding of the mobile boom (1) avoiding any contact with the corresponding fixed rail (3), the tilting of the movable rail (1) being made with respect to the upper support roller (8)

The advantages are apparent from the description.
