Definitions

  • the invention relates, in general, safety equipment related to the exercise of a professional activity.
  • the invention relates to a step device usable on a vehicle and comprising at least one fixed support, a step, and a detector for detecting the occupation of walking by a person.
  • this detection is used, in accordance with the regulations in force, to ensure the safety of the operators present on the step by producing the stop of the automatic cycle. of the body and prohibiting the vehicle from driving more than 30 km / h as well as reversing.
  • the step is made retractable by means of a parallelogram linkage equipped with a hydraulic cylinder.
  • This solution which uses twelve joints, has a disproportionate complexity compared to the desired functionality.
  • the inactive position of the step is used as indicative of the absence of operator.
  • this solution presents the disadvantage of having to raise and lower the walk at each collection point.
  • this operation is inconvenient for the operators, the latter eventually neutralize the means that make it necessary, and perform their work outside any security conditions.
  • a third known device described in the patent document DE 39 18 971 , has electrical switches directly associated with the step or handles or “handrails" for operators, combined with light curtains with optical or ultrasonic sensors, or even sensitive mats sandwiched in the step tray.
  • the detection components are very quickly and very often out of order.
  • the presence of the operator on the step is detected by photocells or similar sensors, having in practice the same disadvantages as the second example mentioned above.
  • the invention therefore aims to overcome all these technical disadvantages while allowing compliance with the safety conditions defined by the regulations in force.
  • the device of the invention is essentially characterized in that it further comprises a mobile bracket at right angles connecting the step to the fixed support and having a substantially horizontal distal section and a substantially vertical proximal section, in that the step is supported by the distal end of the distal section, in that the proximal section shares with the fixed support a mutual articulation zone and a zone of mutual support, the bearing zone being disposed below the articulation zone, in that the proximal section is rotatably mounted on the fixed support, around a tilting axis arranged in the zone d articulation, with an angular displacement of mechanically controlled amplitude, and under the combined effect of a load possibly carried by the step or by the distal section of the movable support and an electric force Antagonist ant tending to raise the distal end of the mobile support and sized to be both not null and overcome by a minimum value charge, and in that the detector is connected to the fixed bracket at right angles connecting the step to the fixed support and having a substantially horizontal distal section and
  • the minimum value of the load is preferably chosen to be equal to a fraction of the average weight of an adult person, for example of the order of 30 kg.
  • the mobile support adopts, under the combined effect of the elastic force and the possible load represented by the presence of these operators, the one or the other of two positions determined in a safe way and easily detectable by electrical, electronic or similar components, guaranteeing the safety of the operators.
  • the step is rotatably mounted on the movable support between an erect inactive position and a substantially horizontal functional position in which it adopts a stable and reversible state.
  • the step may be articulated on the distal end of the distal section by means of a spring joint and beyond the alignment position.
  • This arrangement avoids the operators the inconvenience caused by the known devices in which the walking is always systematically moved between two positions, while allowing them to place the walk in the inactive position if they wish.
  • one of the supports has an oblong slot centered on the tilting axis, that the other support has a lug engaged in the oblong slot, and that the angular displacement of the movable support relative to the fixed support is thus determined by the movement of the pin in the light.
  • the movable support In case of occupation of the step or the distal end of the mobile support by a person, the movable support preferably comes in open stop on the fixed support under the combined effect of the load that represents at least a portion of the weight of this person, and the elastic force, this arrangement to ensure that the operator on the market does not feel any instability resulting from the application of an elastic force opposing its weight.
  • At least one of the fixed and movable supports may advantageously comprise a casing covering the connection area of these supports and prohibiting the insertion of a relative blocking wedge of these supports.
  • the distal section is connected to the lower end of the section.
  • the mobile support constitutes a lever of the second type.
  • distal section is connected to the upper end of the proximal section, and that the movable support is a lever of the first type.
  • the elastic force can be developed by a stack of "Belleville” type spring washers prestressed in compression, this stack being interposed between the supports in the bearing zone.
  • the movable support may comprise a web arranged radially with respect to the tilting axis and facing the stack of washers, to which it retransmits the load possibly carried by the step or by the mobile support.
  • the invention also relates to a dump vehicle, for example for the collection of waste, this vehicle being characterized in that it is equipped with a step device as defined above.
  • the invention relates to a step device intended, in its preferred application, to equip a vehicle for collecting waste.
  • This device comprises, in a manner known per se, a fixed support 1, a step 2, and a detector 3 able to detect the occupation of the step 2 by a person P (FIG. 2).
  • the device of the invention further comprises a mobile support 4 shaped at right angles and connecting the step 2 to the fixed support 1.
  • This mobile support 4 has a section 41 relatively distant from the fixed support 1 and substantially horizontal, and a section 42 relatively close to the fixed support 1 and substantially vertical.
  • the step 2 is articulated on the distal end 410 of the distal section 41, that is to say on the end of this section which is furthest from the fixed support 1, so as to be movable between a functional position substantially horizontal and an inactive standing position.
  • the articulation 5 of the step 2 on the distal end 410 which is for example a joint beyond the alignment position also called “toggle” is equipped with a spring 51 attached to the nose 20 of the step 2 and a bracket 510 of the support 4.
  • the step 2 adopts, in its functional position, a stable state but nevertheless reversible at will by rotation of this step 2 about the axis 50.
  • the proximal section 42 of the mobile support 4 shares with the fixed support 1 a zone of mutual articulation Z1 and a zone of mutual support Z2.
  • the proximal section 42 of the mobile support 4 is rotatably mounted on the fixed support 1, around a tilting axis Y.
  • tilting due to the fact that it has an angular displacement of mechanically controlled amplitude, typically less than 5 degrees and for example of the order of 2 degrees .
  • one of the supports for example the fixed support 1
  • the other support in this case the mobile support 4
  • the tilting of the mobile support 4 around the Y axis relative to the fixed support 1 is subjected to the combined effect of a load possibly carried by the step 2 or the distal section 41, and a force antagonistic elastic tending to raise the distal end 410 of the mobile support 4.
  • the possible load is typically constituted by the weight of a person P occupying, if necessary, the step 2 or the distal section 41 of the mobile support 4, and the elastic force is dimensioned so as to be both non-zero and overcome by a load of minimum value, of the order of 30 kilograms for example.
  • the elastic force must possibly have a high value if it is exerted near this tilting axis.
  • this elastic force is for example developed by a stack 6 of elastic washers of "Belleville” type prestressed in compression, this stack being disposed in the bearing zone Z2 and interposed between the fixed support 1 and the mobile support 4 .
  • the mobile support 4 may for example comprise a web 45 arranged radially with respect to the tilting axis Y and opposite the stack 6 of washers, to which it retransmits, with a multiplicative factor of lever arm, the charge P possibly carried by the step or by this mobile support, that is to say typically the weight or a fraction of the weight of a person P.
  • the detector 3 is connected to the fixed support 1 and disposed in the bearing zone Z2.
  • the "fixed support” is understood here as encompassing any element supporting the mobile support 4 or any integral part of this element, the detector 3 can therefore be attached to the vehicle when the device of the invention is mounted on the latter.
  • the detector 3 which may for example be constituted by a sealed electrical contact or a proximity sensor, is capable of detecting the rotation of the mobile support 4 around the tilting axis Y under the combined effect of the force elastic developed by the stack 6 and the load exerted against this elastic force and constituted by the weight the person P.
  • the elastic force pushes the lug 43 against the upper edge of the oblong slot 10 in the rest position of the device, that is to say in the case of the unoccupied step 2, whereas, in the opposite case illustrated in FIG. 2, the load constituted by the weight of the person P overcomes the effect of the elastic force and pushes the pin 43 towards the lower edge of the oblong slot 10.
  • the mobile support 4 in the event of occupation of the step 2, come into abutment on the fixed support 1 in the support zone Z2 to optimize the comfort and stability of the person P.
  • one and / or the other of the fixed and movable supports 1 and 4 may be provided with a housing 44 covering the connection area of these supports and prohibiting the insertion of a wedge that would be intended to ensure the relative locking of these supports.
  • FIGS. 1 and 2 show an embodiment in which the distal section 41 of the mobile support 4 is connected to the lower end of the proximal section 42.
  • the mobile support 4 constitutes a lever of the second type with respect to the load constituted by the weight of the person P, the resistance applied by the stack 6 of spring washers, and the rotation point constituted by by the tilting axis Y.
  • the invention could nevertheless be implemented by connecting the distal section 41 of the mobile support 4 to the upper end of the proximal section 42, for example at the height of the tilting axis Y.
  • the mobile support 4 would then constitute a lever of the first type vis-à-vis the load constituted by the weight of the person P, the resistance applied by the stack 6 of elastic washers, and the point of rotation constituted by the tilting axis Y.
