Definitions

  • the present invention relates to a device for fixing a running rail such as a handling rail.
  • the present invention also relates pieces, and in particular flat or platinum and cap, part of this fixing device.
  • a first element which rests on the surface of the support generally flat and securely attached to it by welding;
  • a second element which makes it possible to imprison the rail, more particularly the sole or the shoe of the rail, and which has for example a lateral surface overhanging and coming into contact with the sole or the shoe of the rail;
  • a third element which corresponds to a means of fixing the first and second elements together.
  • this third element is constituted by a screw whose head is inserted into a present opening in the first and in the second element and on which comes to fix a nut.
  • the welding systems present as main drawback the need to provide a room that we will weld on the plate or the plate, which increases the cost price of the fixation.
  • the fact of using such welded devices makes the user dependent on the dexterity or skill of the welder.
  • a last disadvantage is the weight of such a device, given that it requires the presence of an additional room.
  • the main difficulty in using bolted systems is that the screw head is drowned in concrete and it is no longer possible to have access to consider dismantling the device. he it is essentially a single use system.
  • the present invention aims to provide a track rail fixing device which prevents disadvantages of the two prior art systems, that is, it must be a device not requiring no welding but whose disassembly is however allowed.
  • the present invention relates to a device for fixing a running rail such as a handling rail on a support comprising at least one plate or a plate on which the rail rests and two elements, a primary element intended for fixing the rail sole and a secondary element corresponding to a screw-nut assembly, the screw comprising a body and a head screw, characterized in that the plate or the plate has openings which are shaped so as to allow the insertion of the screw head according to a first direction for so-called direction or position of introduction while preventing its exit after a movement imposed on said screw head in a second direction or position called direction or position of blocking.
  • the movement imposed on the screw head can be a rotation or a translation.
  • a rotation so we make a movement between the first direction (of introduction) and the second direction (of blocking).
  • a translation we therefore perform a movement between the first (introductory) position and the second position (blocking).
  • the device comprises in in addition to a tertiary element at the level of which positioned the screw head, and shaped as it allows movement of the screw head between the direction or so-called introductory position and direction or position so-called blocking and vice versa.
  • This element tertiary advantageously allows disassembly to be authorized, even if the screw head fitted with the element tertiary is embedded in the environment (concrete, earth, mud, etc.).
  • the conformation of the element tertiary is such that it also helps prevent the exit of the screw after the movement imposed on said head screw in direction or locking position.
  • the tertiary element is a cap comprising protusions with buffer surfaces between which the screw head can rotate (by rotation) or move (per trip).
  • the cap comprises in besides anchoring means in the opening of the dish or platinum which are preferably in the form outgrowths.
  • the openings in the dish or platinum have an oblong shape.
  • Oblong shape means a shape elongated and preferably an ellipse.
  • the openings in the dish or platinum have the form called "keyhole”, that is to say a shape responding to an asymmetrical design particular.
  • the shape of the openings of the dish or the platen is such that the dimensions said openings are larger in the direction or introductory position only in the direction or position blocking, so that the screw head cannot be introduced into the opening concerned only according to the direction or position of introduction. Furthermore, in order prevent the screw head from coming out of the opening direction or locking position, the dimensions of opening in this direction or blocking position will be smaller than those of the screw head.
  • Such openings will be obtained by conventional cold steel processing techniques such as punching, laser cutting, flame cutting, waterjet, plasma cutting or even milling.
  • the secondary element constituting the screw-nut assembly may possibly be equipped with accessory elements such as washers.
  • flat is meant a relatively long, which can reach up to six meters, on which is continuously deposited the rail.
  • platinum we hear a shorter element that can be used for mounting a rail discontinuously, i.e. the rail is placed on several plates separated by spacings.
  • These dishes or these plates are made of preferably in laminated sheet having a thickness relatively constant and preferably between 15 and 20 mm. These sheets can be obtained by cutting (oxycutting, laser cutting, water jet, etc.).
  • the dishes or plates include other openings for others functions such as upgrading.
  • the present invention also relates to a dish or a platinum intended to be used in the fixing of a running rail such as a handling on a support using the device according to the invention.
  • this dish or platinum includes openings that are shaped to allow inserting the head of a screw while preventing exit thereof after a movement imposed on said head quote.
  • the openings have a shape oblong or a "keyhole" shape.
  • the present invention relates also to a cap intended for use in the fixing of a running rail such as a handling on a support using the device according to the invention.
  • This cap allows the movement of a head of screw between the direction or insertion position and the blocking direction or position and vice versa. he thus helps to prevent the exit of the screw head after this movement.
  • the cap includes protusions with buffer surfaces. It includes besides anchoring means in the opening of the dish.
  • Figure 1 shows an exploded view of different elements of the fixing device according to the present invention.
  • Figure 2 shows a sectional view of different elements of the fixing device according to the present invention with respect to the rail to be fixed.
  • Figure 3 shows a sectional view of a preferred embodiment of a cap according to the present invention.
  • Figure 4a shows a top view of this preferred embodiment of the cap according to the present invention with the screw head such than originally introduced.
  • Figure 4b shows a top view of this preferred embodiment of the cap in the dish according to the present invention with the screw head which has undergone 90 ° rotation in the locking direction.
  • the primary element 1 comprises so classic an extension 9 intended to be superimposed on the sole or pad 10 of the rail.
  • This extension 9 includes on its lower part an elastic member 11 produced in a elastomeric material which absorbs the movements of the rail.
  • the primary element 1 further comprises in all its thickness an opening 12 perpendicular to the plane of the plate 4 and in which the screw is positioned 2 which, with its nut 6 constitutes the secondary element 2.
  • the secondary element 2 thus makes it possible to secure the primary element 1 on the plate 4.
  • the plate 4 has in its thickness a opening 7 above which the element is positioned primary 1.
  • the opening 7 at the level of the dish 4 has a shape oblong as shown in Figure 1.
  • This shape 7 has a minor axis 71 and a major axis 72.
  • the screw 2 as shown in FIG. 1 which has a body and a screw head, has an axis of the screw body constituting the main axis screw rotation.
  • the relative dimensions of the screw head 20 and the opening 7 of the dish 4 are such that the head of screw can only be inserted into opening 7 according to the major axis 72 of said opening, the smallest dimension of the screw head being less than the minor axis 71 while that the largest dimension of the screw head is greater than minor axis 71.
  • Tertiary element 3 can take the form a cap, preferably made of synthetic material.
  • the cap 3 has a base 14 in the center of which will be fixed the screw head, an intermediate zone 15 and outgrowths 16 in the form of notched tenons (in the form of half-T), which outgrowths 16 are capable of fit into notches (not shown) made in level of the opening 7 of the dish or possibly directly in this opening 7 of the dish, and not to stand out only with difficulty.
  • the cap 3 has in its thickness of the locking means corresponding to protrusions 18,18 'which extend from base 14 to the intermediate zone 15 and which have stop surfaces A, A '.
  • Figures 3, 4a and 4b show, as illustration, a preferred embodiment of the element tertiary according to the invention corresponding to a cap, but they in no way limit the scope of the invention.
  • Plate 4 may have other openings complementary to opening 7 and which will fill other functions, such as for example upgrading.
  • the second element may also include accessory elements such as washers 17 placed between the surface of the primary element 1 and the nut 6 to tighten screw 2 as well as possible with its nut in the element primary 1 and dish 4 and thus ensure better solidarity between the two.
  • accessory elements such as washers 17 placed between the surface of the primary element 1 and the nut 6 to tighten screw 2 as well as possible with its nut in the element primary 1 and dish 4 and thus ensure better solidarity between the two.
  • Such a device therefore ensures a very large fixing security.
  • it has the advantage to be easily removable.
