Definitions
- the present invention relates to a device for fixing a running rail such as a handling rail.
- the present invention also relates to the parts, and in particular to the plate or plate and to the cap, forming part of this fixing device.
- soldering systems use is made of a first element which bears on the surface of the generally flat support and which is firmly fixed thereon by welding; (n) a second element which makes it possible to trap the rail, more particularly the sole or the shoe of the rail, and which has for example an overhanging lateral surface and coming into contact with the sole or the shoe of the rail, (m) a third element which corresponds to a means of fixing the first and second elements to each other.
- this third element is constituted by a screw, the head of which is introduced into an opening present in the first and in the second element and on which a nut is fixed.
- Welding systems have as main drawback the need to provide an additional part that will be welded to the plate or the plate, which increases the cost price of the fixing device.
- the fact of using such welded devices makes the user dependent on the dexterity or skill of the welder.
- a final drawback is the weight of such a device, since it requires the presence of an additional part.
- Document FR 2 500 500 describes a steel cross member for railway superstructures comprising an upper plate, folded side flanks and connecting on both sides of the upper plate and feet connecting to each lateral flank and which extend parallel to the upper plate.
- the top plate has a groove and openings. Said groove is arranged on the lower side of the upper plate. It is open at the bottom and its cross section corresponds to that of the head of a fixing screw.
- fixing screws are used which are introduced by their head into the crosspiece at the openings, bringing out said heads at the groove and the screws are blocked by making them be rotated 90 °.
- Document GB 1 575 654 describes a dish for fixing a rail rail to a support, said dish comprising two jaws opposite one another, directed towards the lateral face of a rail so as to delimit therebetween a groove intended to receive a bolt and narrowed upwards.
- This groove comprises a bottomless slot opening onto a thin base connecting the jaws and having a recessed part which is connected to the groove.
- the groove has its largest width at the bottom and its smallest width at the top. It is furthermore provided with stepped shoulders between its lower part and its upper part.
- the present invention aims to propose a device for fixing running rails which avoids the drawbacks of the systems of the prior art, that is to say, it must be a device which does not require welding but whose dismantling is however authorized.
- 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 to the fixing of the sole of the rail and a secondary element corresponding to a screw-nut assembly, the screw comprising a body and a screw head, characterized in that the plate or the plate has openings which are shaped so as to allow 1 insertion of the screw head in a first direction or position called direction or insertion position while preventing its exit after a movement imposed on said screw head in a second direction or position called direction or blocking position, the device further comprising a tertiary element at the level of which the screw head will be positioned, and of conformation such that it allows the movement of the screw head between the direc tion or so-called introduction position and the direction or so-called blocking position and vice versa.
- this tertiary element advantageously allows disassembly to be authorized, even in the case where the screw head provided with the tertiary element is embedded in the environment (concrete, earth, mud, etc.).
- the movement imposed on the screw head can be a rotation or a translation. In the case of a rotation, a movement is therefore made between the first direction (of introduction) and the second direction (of blocking). In the case of a translation, we therefore perform a movement between the first position (introduction) and the second position (blocking).
- the conformation of the tertiary element is such that it also contributes to preventing the exit of the screw after the movement imposed on said screw head in the blocking direction or position.
- the tertiary element therefore has a double blocking and reservation function (unblocking).
- the tertiary element is a cap comprising protrusions having stop surfaces between which the screw head can rotate (by rotation) or move
- the cap further comprises means for anchoring in the opening of the dish or the plate which are preferably in the form of protuberances.
- the openings in the dish or the plate have an oblong shape.
- oval shape means an elongated shape and preferably an ellipse.
- the openings present in the dish or the plate have the form called "keyhole”, that is to say a shape responding to an asymmetrical design particular.
- the shape of the openings of the plate or of the plate is such that the dimensions of said openings are larger in the direction or position of introduction than in the direction or position of blocking, so that the screw head can only be inserted into the opening concerned according to the direction or position of introduction. Furthermore, in order to prevent the screw head from coming out of the opening in the blocking direction or position, the dimensions of the opening in this direction or blocking position will be smaller than those of the screw head.
- Such openings will be obtained by conventional techniques of cold steel implementation such as punching, laser cutting, one flame cutting, cutting by j and water, by plasma or even milling.
- the secondary element constituting the screw-nut assembly may optionally be equipped with accessory elements such as washers.
- flat means a relatively long element, which can reach up to six meters, on which is continuously deposited the rail.
- plate is meant a shorter element which can be used for mounting a rail in a discontinuous manner, that is to say that the rail is deposited on several plates separated by spacings.
- dishes or these plates are preferably made of laminated sheet having a relatively constant thickness 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 other functions such as leveling.
- the present invention also relates to a dish or a plate intended to be used in the fixing of a running rail such as a handling rail on a support using the device according to one invention.
- this dish or plate includes openings which are shaped so as to allow the insertion of the head of a screw while preventing the exit thereof after a movement imposed on said head
- the openings have an oblong shape or a "keyhole" shape.
- the present invention also relates to a cap intended to be used in the fixing of a running rail such as a handling rail on a support using the device according to the invention.
- This cap allows the movement of a screw head between the direction or position of introduction and the direction or position of blocking and vice versa. It thus helps to prevent the exit of the screw head after this movement.
- the cap comprises protrusions having stop surfaces. It further comprises means for anchoring in the opening of the dish.
- the tertiary element can be advantageously used for fixing a running rail in the device according to the present invention, it can, in particular when it takes the form of a cap, have further other applications and be used as a blocking and reservation element in other fastening devices.
- the present invention also relates to a method of fixing a running rail, such as a handling rail, on a support, characterized in that it uses the device according to the present invention, the dish or the plate according to the present invention, or the cap according to the present invention.
- Figure 1 shows an exploded view of the various elements of the fixing device according to the present invention.
- 2 shows a sectional view of the various elements of the fixing device according to the present invention relative to the rail to be fixed.
- FIG 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 as initially 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 been rotated 90 ° in the locking direction.
- the fixing device comprises at least one plate or a plate 4 and three elements:
- the secondary element which corresponds to an assembly consisting of a screw 2 with its nut 6 and which makes it possible to secure the primary element 1 and the plate 4, the screw 2 itself comprising a body 21 and a screw head 20;
- the tertiary element 3 which cooperates with the screw head 20 and possibly participates in controlling the movement of said screw 2.
- the tertiary element 3 above all performs a so-called "reservation" function, that is to say that it allows the primary element 1 to be separated as desired and the plate 4 while allowing the screw head 20 to be released.
- the primary element 1 conventionally comprises an extension 9 intended to be superimposed on the sole or pad 10 of the rail.
- This extension 9 comprises on its lower part an elastic member 11 made of an elastomeric material which makes it possible to absorb the movements of the rail.
- the primary element 1 further comprises throughout its thickness an opening 12 perpendicular to the plane of the plate 4 and in which is positioned the screw 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 to the plate 4.
- the plate 4 has in its thickness an opening 7 above which the primary element 1 is positioned.
- the opening 7 at the level of the plate 4 has an oblong shape as shown in Figure 1. This shape
- the screw 2 as shown in Figure 1 which has a body and a screw head, has an axis of the screw body constituting the main axis of rotation of the screw.
- the relative dimensions of the screw head 20 and the opening 7 of the plate 4 are such that the screw head can be introduced into the opening 7 only along the major axis 72 of said opening, the smallest dimension of the screw head being less than the minor axis 71 while the largest dimension of the screw head is greater than the minor axis 71.
- the tertiary element 3 can take the form of a cap, preferably made of synthetic material.
- the cap 3 has a base 14 in the center of which the screw head will be fixed, an intermediate zone 15 and protrusions 16 in the form of notched tenons (in the form of a half-T), which protrusions 16 are capable of fitting into notches (not shown) made at the opening 7 of the dish or possibly directly in this opening 7 of the dish, and to come out only with difficulty.
- the cap 3 has in its thickness blocking means corresponding to protrusions 18, 18 ′ which extend from the base 14 to the intermediate zone 15 and which have abutment surfaces A, A ′.
- FIGS 3, 4a and 4b show, by way of illustration, a preferred embodiment of the tertiary element according to the invention corresponding to a cap, but they do not limit the scope of the invention .
- the fixing of the rail 5 to the flat 4 is done as follows:
- the cap 3 is first fixed under the dish 4 by fitting the protrusions 16 of the cap 3 into the notches of the opening 7 (or directly in the opening 7) of the dish 4.
- One end of the cap 3, more precisely the upper end is thus secured to the surface (lower) of the plate 4 and the other end, the lower end, is located under said plate 4.
- the stop surfaces A, A 'of the protrusions 18,18' at the level of the cap 3 are thus oriented in the direction of introduction B.
- the screw head 20 is introduced into the opening 7 in a first direction I corresponding to the direction of introduction.
- the screw head 20 has dimensions such that the screw can pass through the thickness of the dish and position itself at the level of the base 14 of the cap 3.
- the relative position of the screw head 20 with respect to the various elements of the cap 3 thus obtained is shown in FIG. 4a.
- the primary element 1 is placed above the plate 4 in inserting the screw 2 into the opening 12 of the primary element 1.
- the screw is long enough to pass through the entire thickness of the primary element 1.
- the system is finally locked with the nut 6 fixed on the opinion.
- the dish 4 may have other complementary openings of the opening 7 and which will fulfill other functions, such as for example the leveling.
- the second element may further include accessory elements such as washers 17 placed between the surface of the primary element 1 and the nut 6 to best screw the screw 2 with its nut in the primary element 1 and the dish 4 and thus ensure a better connection between the two.
- Such a device therefore provides very high security of attachment. In addition, it has the advantage of being easily removable.
- the primary element (1) is entirely conventional. All the effectiveness of such a device rests solely on the sole skill of a person skilled in the art for making the opening 7 at the level of the plate 4.
- the device according to the present invention has the advantages following. On the one hand, it facilitates the packaging and delivery of the dishes and, on the other hand, the dishes are of simpler design since the welding of the parts is no longer necessary. Furthermore, the amplitude of adjustment is greater and the overall height is reduced.
- the device according to the present invention is suitable for all types of mounting on concrete: continuous plates, discontinuous or mixed sleepers. It is also suitable for all tracks on the ground, protruding or in a gutter. It can be used in installations such as port and multimodal installations, shipyards, automated stores, circular routes, ...
