Description

The present invention relates to a system for securing the entry / exit passages of a staircase / mechanical carpet.

Securing this type of transport mechanism poses a number of problems today. It is known that, for example, when such a staircase / conveyor belt is out of order and an intervention is planned or is in progress, access to these stairs / carpets is prohibited by means of barriers equipped with means of support. .

It is understandable that this is not satisfactory.

The object of the invention is therefore to solve these problems.

To this end, the subject of the invention is a system for securing the entry / exit passages of a staircase / mechanical mat, characterized in that it comprises portal-shaped means implanted at the input and / or at the output of the staircase / carpet, comprising means in the form of lateral uprights whose upper ends are connected by transverse box-shaped means, in which are housed means forming a metal curtain movable between a retracted position in the box-shaped means to allow access to the staircase / carpet and an active position deployed from the cross-box-shaped means between the means in the form of lateral uprights of the portal-shaped means, to prohibit access to the staircase / carpet.

The invention will be better understood with the aid of the following description given solely by way of example and with reference to the appended drawings, in which:

• the figure 1 represents a schematic perspective view of an exemplary embodiment of a security system according to the invention, and
• the figure 2 represents a side view of it.

Indeed, these figures show a system for securing the entry / exit passages of a staircase / mechanical carpet.

This is for example designated by the general reference 1 in these figures, an end of this escalator / mechanical mat being for example associated with a landing plate designated by the general reference 2.

In fact, the system according to the invention comprises gantry-shaped means, designated by the general reference 3, located at the entrance and / or at the exit of the staircase / carpet and having means in the form of lateral uprights such as, for example the means designated by general references 4 and 5 on the figure 1 , whose upper ends are connected by transverse box-shaped means, designated by the general reference 6.

As can be seen more particularly on the figure 2 , metal curtain means are housed in these box-shaped means transverse, these curtain means being designated by the general reference 7 in this figure, and being movable between a retracted position in the box-shaped means to allow access to the stair / carpet and an active position deployed from the means in the form of a transverse box, between the means in the form of side uprights of the portal-shaped means, to prohibit access to the staircase / carpet.

In fact and as illustrated, the facing edges of the means forming lateral uprights of the gantry-shaped means, that is to say the means 4 and 5, comprise means forming guide rail corresponding edges of the means in form of metal curtain.

For example, in these figures, one of the slides is designated by the general reference 8, for the amount forming means 4.

According to the illustrated embodiment, the means in the form of metal curtain 7 are rotatably mounted in the cross-box-shaped means 6 of the gantry-shaped means, to allow their movements between their active and retracted positions by unwinding / winding those for example under the control of electric motorization means of these displacements.

It goes without saying of course that other embodiments of these metal curtain means can be envisaged.

As will be described in more detail later, the operation of these motorization means can be controlled for example by an information processing unit.

It will also be noted that the edges facing the means forming side jambs of the gantry-shaped means may comprise lighting means and means for detecting the passage of a user in the gantry, in order to control the operation of the staircase / carpet.

For example, means for detecting the passage of a user in the gantry constituted for example passage detection radar means designated by the general reference 9 on the figure 1 , can be envisaged, as well as lighting means constituted for example by light emitting diode ramps such as the ramp designated by the general reference 10, placed in the lower part of the gantry-shaped means and the ramp 11 placed in the upper part thereof.

It should also be noted that the front and / or rear faces of these means forming lateral uprights and / or means forming a transverse box of the gantry-shaped means may comprise means providing information relating to the operating state of the device. stairs / carpets to the users, for example different pictograms such as pictograms designated by the general reference 11 on the figure 1 , placed on the lateral uprights of the gantry or pictograms 12 placed on the transverse box thereof.

Similarly, the transverse box means of this gantry may comprise alphanumeric display means such as that designated by the general reference 13 in this figure, for delivering different information to users.

As illustrated in these figures, these gantry-shaped means may also be equipped with user ramps, such as for example the ramp designated by the general reference 14 in this figure.

This then allows users to be guided to or from the escalator / mechanical mat 1.

Of course, the gantry-shaped means may also be equipped with emergency stopping means for the operation of the stair / carpet, such as for example emergency stop buttons placed on the means in the form of gantry such as the button designated by the general reference 15 in these figures placed on one of the lateral uprights, or the button designated by the general reference 16 placed on one of the ramps thereof.

Finally, it should be noted that these gantry-shaped means can also be equipped with means for taking pictures of the stairs / mats constituted for example by a camera or the like connected to an operations center and allowing for example to this center. operations to monitor or remotely control the operation of the stairs.

Information exchange means between the gantry and for example the center of operations can also be provided.

It is then conceivable that the security system according to the invention has a certain number of advantages over systems of the state of the art.

Indeed, this system can be controlled by an information processing unit managing both the display of various user assistance information, as well as the operation of the metal curtain means for opening or closing access to stairs / carpet.

These gantry-shaped means then group together the various signaling and safety or even control and safety components of the stair / carpet that until now could be dispersed and implanted on different specific organs, which makes it easier to implantation of these.

It will also be noted that the security system according to the invention can implement an information processing unit constituted for example by a programmable logic controller or any other information processing system of this type, making it possible to collect the various information items of the sensors associated with this system, such as, for example, position sensors of the curtain-shaped means, the radar for detecting the passage of a user or the emergency stop buttons, for controlling the operation of the means of signaling, means of displaying information, or even means of motorization of the curtain.
