Definitions

  • the present invention relates to a rail protection device of variable dimensions for a rail for anchoring equipment in transport means that may be an aircraft.
  • existing rail protection devices are made up of section member segments cut to the dimensions of predetermined intervals that are to be protected. Those devices are not variable and they become unusable in the event of a change in the length of the portion of rail that is to be covered. When modifying the space that is to protected, it then becomes necessary to cut new devices to the appropriate length or to add or remove section member elements, thereby requiring a return to a workshop and degrading the effectiveness with which the rail protection function is performed, since adding and removing elements weakens protection against aggression.
  • the present invention makes it possible to remedy those drawbacks since the protection device can be lengthened or shortened at will in order to be fitted accurately to the portion of rail that is to be protected without any need to add or remove an element or to install a new device cut to the right size.
  • This device of dimensions that can be varied at will, is a device that saves time since its modularity on demand can be used quickly on site. It can be reused as many times as desired by means of the installation and removal mechanisms that are described below.
  • the device guarantees that the portion of rail on which it is installed is protected against any aggression.
  • the device may be preadjusted before being installed in the rail by using dimension information marked on one of its faces in order to guide the operator.
  • An advantage of the device is that its dimensions can be varied at will regardless of the length of the rail to be protected, and it is thus reusable as desired while conserving its integrity and its properties.
  • the device In order to provide effective protection for the portion of rail between two equipment anchor points, the device must be capable of being fitted accurately to the interval between those two points, which interval may be variable.
  • Another advantage of this device lies specifically in fitting it to the interval between two equipment anchor points, since the device can be extended as a function of the rail portion that is to be protected.
  • Another advantage of this device is that it can be fastened in the rail, whatever the location on the rail, and it becomes clamped so as to be held in place.
  • One more advantage of this device is that it can be preadjusted to a given length and can thus act as an abutment or as a measurement element for determining an interval for the purpose of fastening other pieces of equipment at desired intervals in the rail.
  • the device may be fastened in releasable or permanent manner and/or in hinged manner to pieces of equipment, and once its length has been adjusted, it may be positioned in the rail in order to act as an abutment for the following piece of equipment that is to be installed in the rail.
  • This optionally preadjusted device when fastened in permanent manner to one of the pieces of equipment, may become locked in position on the rail by the piece of equipment that overlies it.
  • This preadjustment can make it possible, when the rail protection device is already in place in the rail and without it being limited by anchor points, for the rail protection device to be used as a template or an abutment for pieces of equipment that are to be fastened at desired intervals.
  • the device is designed in such a manner as to be held in the rail in complete safety.
  • the rail protection device may be made up of one or more elements that are connected to one another in such a manner as to be held captive and to ensure, regardless of the extent to which they are deployed, that the device is locked, possibly by self-locking in the rail, merely by deploying its elements, and it can perform all of the functions of protecting the rail against any type of aggression.
  • At least one element incorporating one or more elements that may for example be deployed in connection with one another, including at least one element that is in contact with the slot of the rail so as to become inserted, e.g. in the half-recesses of a rail, which may be of the airplane type, and be capable of being fastened by means of at least one anchor point at one or more locations of the rail portion to be protected.
  • the portion penetrating into the slot of the airplane type rail may be made up of one or more subassemblies suitable for matching the shape of the recesses of the rail and/or the internal slot of the rail.
  • One or more elements of the protection device may overlap and slide, by means of complementary grooves, so as to cover the apparent spaces of the rail in order to protect them from aggression.
  • These sliding elements may be graduated to provide information about the desired dimensions and to enable adjustment prior to being installed on the rail.
  • the protection device also acts as a template for the desired intervals.
  • an optionally removable locking system possibly in a remote controlled system, that is situated at least one end of the protection device, holds the device in place in the rail.
  • the rail protection device is made up of: two elements (A, D) that deploy in connection with each other, at least one element is in contact with the slot (r 1 ) of the rail (R) so as to become inserted in the recesses ( 3 , 3 ′) of the rail (R) and so as to be capable of becoming fastened by means of at least one anchor point ( 4 , 5 , 6 , 7 ) at one or more locations of the rail portion (R) that is to be protected.
  • the device is made up of a stationary element (A) and a movable element (B), that may remain connected together.
  • the element (A) includes a peg ( 4 ) for inserting in the recess ( 3 , 3 ′) of the rail (R) and one or more parts ( 5 ) that become inserted in the interval ( 8 ) that extends between two recesses ( 3 , 3 ′).
  • the peg ( 4 ) has the shape of a recess.
  • the part ( 5 ) has a rod ( 11 ) passing longitudinally therethrough and passing through the centers of two guides ( 12 , 12 ′).
  • the function of the spring ( 15 ) consists in pushing away the part ( 5 ) that becomes inserted in the interval ( 8 ) in order to hold the stationary element (A) in the rail on the x-x′ and y-y′ axes.
  • the element (B) slides by means of a groove ( 2 , 2 ′) on each of its sides, the grooves receiving the splines ( 1 , 1 ′) situated on each of the sides of the element (A).
  • the element (B) is provided at one end with a stud ( 6 ) situated at a distance from the peg ( 7 ) such that this distance is equal to half the distance between two recesses ( 3 , 3 ′).
  • the peg ( 7 ) is retractable.
  • the peg is made of material that can react to a magnet.
  • the peg ( 7 ) is situated in a blind well ( 16 ) that does not open out into the top portion of the movable element (B).
  • the peg ( 7 ), held captive in the well ( 16 ), can move freely within the space of the well.
  • the peg ( 7 ) projects from the open end of the well ( 16 ) when it is subjected to the effect of pressure from the spring ( 17 ).
  • the peg ( 7 ) projecting from its housing has the effect of blocking the movable element (B) in any recess ( 3 , 3 ′).
  • movement in translation against the force of the spring ( 17 ) is performed by placing a magnet ( 18 ) of sufficient power to pass through a wall constituted by the blind end of the well ( 16 ) and counter the force of the spring ( 17 ) so as to raise the peg ( 7 ) against the blind end of the well.
  • the element (A) and the element (B) have smooth surfaces without any apparent possibility of disassembly such as a screw, a nut, or a slot for use by any tool. These characteristics constitute a guarantee against any malicious action, degradation, domestic accident, or dirt collection that might prevent operation.
  • the presence of the magnet ( 18 ) makes it possible to move the movable element (B) of the rail protection device in translation.
  • the rail (R) being covered by the rail protection device provides sealing by means of sealing gaskets (d 1 , d 2 , d 3 , d 4 ) against the side edges of the elements (A, B).
  • the stud ( 6 ) co-operates continuously in making the rail protection device secure in connection with the peg ( 7 ) that, under the attraction of the magnet ( 18 ), compresses the spring ( 17 ), retracts into the well ( 16 ), and at this instant the stud ( 6 ) slides in the rail (R), constraining the rod ( 11 ) to move the part ( 5 ) towards a recess ( 3 , 3 ′) and enabling the device to be released from the rail.
  • the movement in translation of the element (B) performed by means of the magnet ( 18 ) enables the element (A) to be overlapped until it is completely covered.
  • the peg ( 7 ) becomes extracted from the recess ( 3 , 3 ′)
  • the stud ( 6 ) comes into contact with the end of the rod ( 11 ) and moves the rod ( 11 ) in translation through half an inch, thereby compressing the spring ( 15 ), which moves the part ( 5 ) in translation, thereby enabling the rail protection device to be released completely.
  • the positions of the recesses covered by the rail protection device may be made apparent in any way, possibly by means of a graduation ( 19 , 19 ′, 19 ′′).
  • a graduation that is apparent on the element (B) informs the user with the magnet ( 18 ) so as to guide the user about the position of the well ( 16 ), which is not apparent on the top portion of the movable element (B).
  • the protection device also serves as a template for determining the desired intervals.
  • FIG. 1 shows the protection device when deployed; seen from above.
  • FIG. 2 shows the protection device when not deployed; seen from below.
  • FIG. 3 shows the protection device when deployed; seen from below.

  • the pieces of equipment (E, E′) are locked in the airplane rail (R) using a fastener system that is specific thereto.
  • the stationary element (A) On its inside face, the stationary element (A) is provided with a centralizer (a 2 ) that is inserted in the slot of the rail (R).
  • the centralizer (a 2 ) serves to hold the rail protection device in place on the axis y-y′.
  • a shape memory fork (a 3 ) operating on the y-y′ axis and provided with two lugs (a 4 -a 4 ′) that become inserted in graduated-position notches (b 2 -b 2 ′, b 3 -b 3 ′, b 4 -b 4 ′) that are situated on the inside face of the slidable element (B).
  • Each notch (b 2 -b 2 ′, b 3 -b 3 ′, b 4 -b 4 ′) corresponds to a graduation value ( 19 , 19 ′, 19 ′′).
  • the shape memory fork (a 3 ) is provided with two lips (a 5 , a 5 ′) that, when they are clamped together, serve to move the lugs (a 4 -a 4 ′) towards each other so as to disengage them from the notches (b 2 -b 2 ′, b 3 -b 3 ′, b 4 -b 4 ′) and release the slidable element (B) relative to the stationary element (A) so as to make it possible to slide it and take it to the desired graduation value and then insert the lugs (a 4 -a 4 ′) in the corresponding notches, thereby fitting the length of the protection device to the distance of the rail (R) to be protected.
  • the rail protection device When the rail protection device is in position in the rail (R) after adjusting the desired distance, it constitutes a positioning template for the piece of equipment (E′).
  • the rail protection device is always secured to the piece of equipment (E) and it becomes locked in the rail (R) when the stud (b 1 ) becomes blocked in a piece of equipment (E′).
