  • truck access area is raised above the unloading area below.
  • the supervisor of the garbage dump or any other person frequently travels to the edge of this dangerous zone which separates the raised area and the area below, which exposes it to permanent dangers related to risks of accidental fall.
  • the publication EP 1 717 124 A1 proposes a system of sliding doors intended to secure the access to the gates of a train car for example.
  • This system comprises at least one fixed console provided with means for guiding said sliding doors and means for controlling said doors arranged to open only the sliding doors facing the boarding gates of said train.
  • Several sliding doors can therefore open simultaneously, which is not the purpose of the present invention where it is sought to allow access to only one dock loading or unloading at a time.
  • the present invention aims to solve this problem by proposing a safety device in the form of a safety barrier provided with two sliding panels retractable one after the other to, firstly protect access to unloading docks and on the other hand release this access to allow the unloading operations of skips while protecting people on the ground.
  • a safety device in the form of a safety barrier provided with two sliding panels retractable one after the other to, firstly protect access to unloading docks and on the other hand release this access to allow the unloading operations of skips while protecting people on the ground.
  • the present invention secures the danger zone which delimits the raised sector and the area below the dump or similar and thus avoids any risk of accidental fall.
  • the invention relates to a safety barrier as mentioned in the preamble, and characterized in that said control and actuation means comprise locking means prohibiting the operation of said panels without a control member arranged to be actuated by an operator and in that said control member is arranged to cooperate with said locking means and allow the successive and alternating displacement of said panels so as to slide said first of said panels parallel to the second of said panels to release access to said first unloading platform and, when said first panel has returned to its original position prohibiting access to said first unloading platform, for sliding said second of said panels parallel to the first to release access second unloading platform.
  • said first and said second panels each comprise suspension-supporting members cantilevered on said central console which comprises corresponding guide elements.
  • Said cantilevered support members advantageously extend over the length of said panels, and said guide members advantageously extend over the width of said central support bracket.
  • said control member is arranged to allow an operator to slide said first panel parallel to said second panel to which it is superimposed, then similarly to allow the operator to slide said second panel parallel to said first panel to which it is superimposed, the operator being during the protected maneuver at the front of the two juxtaposed and superimposed panels.
  • control and actuation means comprise return means arranged to automatically return said first panel or said second panel to their initial position in which they prohibit access to said first or second loading docks, when the operator stops operating said controller.
  • These return means may comprise at least one return spring integral with each panel and coupled on the one hand to a fixed attachment point of said console. central support and secondly at a fixed attachment point of said movable panel by at least one hauling system.
  • Said locking means may comprise at least one latch and latch system, one being provided on said panel and the other on said central support bracket, and at least one being arranged to be actuated by said latching member. command to unlock said panel.
  • said first and said second panels consist of a substantially rectangular frame closed by a grid.
  • said central support bracket comprises a base rigidly fixed to the ground, a vertical column and an upper holding stud fixed to said column, said base and said stud containing rollers of guiding said first and second panels.
  • said base is fixed on a fixed concrete structure which delimits an area corresponding to said unloading docks of a zone below.
  • the present invention relates to a safety barrier 10, specially designed to protect access to unloading docks of a dump, industrial docks loading and unloading goods, or any other type of docks.
  • This security barrier 10 consists of a fixed element which is a central support bracket 11 on which are mounted a first panel 12 and a second panel 13 which are movable and can slide parallel to one another. The two panels 12 and 13 are somehow suspended cantilever on said central support bracket 11.
  • the operator is at the front of the two panels 12 and 13 juxtaposed and superimposed, and is protected against an accidental fall at the rear of the unloading dock which is generally below compared to the before that is in elevation.
  • the operator is protected from reversing operations of the truck because it is no longer positioned at the rear of the truck but far and away from the risk area. Indeed, to open one of the panels 12, 13 releasing one of the unloading platforms, it is obliged to move from the central support bracket 11 to one of the lateral ends of the safety barrier 10 where it is located to direct the driver of the truck.
  • the first panel 12 automatically returns to its initial position by means of return means 30.
  • each panel 12, 13 is defined by a stop 23 provided in the console of central support 11.
  • This stop 23 may consist of a gas cylinder for damping the impact of the panel 12, 13 on arrival, or any other equivalent means.
  • the operator can repeat the operation with the second panel 13 which he accompanies by unlocking it, sliding it parallel to the first panel 12 and moving towards the other lateral end of the safety barrier 10 As before, it remains in a position protected by the two panels 12 and 13 juxtaposed and superimposed, and in a position remote from the maneuvering area of the truck.
  • the return means 30 comprise, in the upper part of the frame of each panel 12, 13, a return spring 31 coupled on the one hand to a fixed attachment point 32 of the central support bracket 11 fixed and secondly at a fixed attachment point 33 of the mobile panel 12, 13, by a hauling system comprising a cable 34 surrounded around at least two pulleys 35, 36 embedded in said panel 12, 13, including a fixed pulley 35 and a movable pulley 36 integral with said return spring 31.
  • the displacement of a panel 12, 13 of its closed position to its open position causes two attachment points 32, 33 to move away by putting the return spring 31 under tension, causing the panel 12, 13 to return to the closed position automatically as soon as the operator removes the body
  • any other equivalent recall means may be suitable.
  • the control member 14 is at the same time a locking member because it prevents the opening manipulation of the panels 12 and 13 by unauthorized persons not provided with said control member 14.
  • each panel 12, 13 is locked in the closed position in the central support bracket 11 by a bolt 24 secured to said panel 12, 13 arranged to be housed in a keeper 25 secured to said bracket 11.
  • the bolt 24 is formed by a V notch provided in a leaf spring 26, one end of which is fixed to the frame of said panel 12, 13 and the other end is free to be lowered by the control member 14 according to the arrow E.
  • the waste 25 is formed by a notch provided in a wall 27 of the central support bracket 11 superimposed on said leaf spring 26.
  • the central support console 11 is therefore equipped with control means and actuating panels 12, 13, which includes the control member 14.
  • control and actuation means could of course be motorized. They could in this case include electrical or electronic locking means actuated by a remote control member such as a remote control or the like, with or without an access code.
  • a remote control member such as a remote control or the like
  • the organ of remote control replaces the manual control member 14 and the central support bracket 11 may constitute a signal support.
  • the panels 12 and 13 are held by cantilevered holding members and guide members 15, 15 'mounted on said central support bracket 11 which may be rail members and rollers for holding the panels 12 and 13 in height and to allow their longitudinal sliding between an open position which frees access to the corresponding unloading platform and a closed position which condemns this access.
  • the guide elements 15 and 15 ' are advantageously mounted respectively on a base 16 of said central support bracket 11 and on an upper holding stud 17 which are connected by a vertical column 18.
  • the central support bracket 11 is advantageously mounted, by its base 16 on a fixed concrete structure 19 which delimits the raised front zone of the rear zone below which are separated by said safety barrier 10.
  • each panel 12, 13 comprises a guide rail 22 in the lower part which slides on rollers 15 provided on said base 16 (cf. Fig. 6 ).
  • Each panel 12, 13 is also guided in the upper part between pairs of rollers 15 'vertical provided on said upper holding pad 17.
  • any other equivalent guide means may be suitable.
  • the panels 12 and 13 are preferably made of metal frames 20 of substantially rectangular shape whose interior is filled with a grid 21, for example sheet punched by stamping.
  • the grid 21 could be replaced by solid elements made of metal or synthetic material or by a grid.
  • the figure 5 shows the safety barrier 10 during operation.
  • the second panel 13 is moved in the direction of the arrow A from the center to the opposite end of the safety barrier 10, parallel to the first panel 12.
  • the rod-shaped control member 14 serves the operator to unlock and slide the panel 13.
  • the removal of the control member 14 causes the automatic return of the second panel 13 in the closed position.
  • the operator can open the first panel 12 in the same way by moving it in the direction of the arrow B from the center to the opposite end of the safety barrier 10
  • the opening control which is described in its manual form, could be automated. It could be associated with an automatic remote control, such as a remote control with or without access code, comprising detection means, so as to allow automated and secure operation, for example by signaling elements and stop means in case of human presence in the area of the unloading docks.
  • the present invention is not limited to the embodiment described but extends to any modification and variation obvious to a person skilled in the art while remaining within the scope of protection defined in the appended claims.
  • the holding and guiding means may be designed in different ways.
