Definitions
- the present invention relates to the field of fixing devices at the end of tubes intended to be pressurized. More specifically, the invention makes it possible to attach an element to the end of a tube, for example a sprinkler on a candle.
- sprinklers can be mounted at the end of a tube called a "candle" to facilitate the positioning of the sprinkler in relation to a water supply pipe on which the candle is fixed.
- the invention can also be used for other types of elements and tubes intended to be pressurized, for example to attach a pressure or temperature sensor to one end of these tubes.
- a sleeve is conventionally used, a first portion of which is fixed at the end of the tube and a second portion carries the element or support means for this element.
- the sprinkler head has a base with a cylindrical portion of smaller diameter, for example between 12 and 15 mm.
- the cylindrical portion of the base has an external thread and the candle also has an external thread.
- a diameter adapter sleeve is then used.
- This adapter sleeve comprises a first portion intended to be screwed onto the external thread of the candle with an internal diameter of 25 mm and a second portion intended to receive the threaded cylindrical portion of the base of the sprinkler.
- this type of fixing requires an element with a bulky base because the latter must have a cylindrical portion on which a thread is attached.
- the height of the base can be problematic.
- the fixing device is complex because it incorporates, in addition to these slender elements, a disk and a nut making it possible to tension the slender elements by using the nut to move the disk on which the slender elements are fixed.
- the invention relates to a device for fixing an element to one end of a tube intended to be pressurized, the tube comprising at least two flats and a threaded portion; the fixing device comprising:
- - a base supporting the element and intended to be attached to the end of the tube; the base comprising at least two anchor points;
- a nut having a thread adapted to the thread of the threaded portion of the tube; the disc having an internal opening whose diameter is greater than the external diameter of the tube and smaller than the external radial dimensions of the nut so that the element can be attached to the end of the tube with the disc placed around the threaded portion of the tube so that the slender elements extend into the flats of the tube, that the screwing of the nut on the threaded portion of the tube moves the disc away from the end of the tube by tensioning the slender elements, and that the tension of the base on the end of the tube resists pressurization of the tube.
- the invention thus allows an operator to quickly mount the element at one end of a tube by placing the disc around the end of the tube so that the slender elements are arranged in the flats of the tube, by arranging the nut on the disk and these elongated elements, positioning the base and the elongated elements on the base, and screwing the nut so as to stretch the elongated elements and press the base against the end of the tube.
- the fixing device also comprises a seal intended to be placed between the base and the end of the tube.
- the tension applied by the slender elements on the base can compress the seal to ensure the desired seal.
- the added element on the end of the tube can be smaller and less expensive to produce because it is no longer necessary for this element to have a base with a threaded cylindrical part because the fixing of the base is now carried out by the tension of the slender elements.
- Each anchor point comprises, for example, at least one lug forming a housing intended to receive a pin fixed to the first end of each elongate element.
- the desired tension can be obtained by a color indicator present on the tube so that the operator knows how far he must move the nut to reach the desired pressure resistance.
- the fastening device may comprise elongated elements whose shape and material make it possible to respond to tensile stresses.
- the plinth can be fixed with two, three or four slender elements.
- the fixing device comprises only two elongated elements intended to cooperate with two diametrically opposed flats on the tube. This embodiment ensures acceptable stability to the base by limiting the number of elongated elements required.
- the nut preferably corresponds to a hexagonal nut, the external radial dimensions of the nut being the dimension between the opposite flats of the nut.
- the internal opening of the disc preferably has flats intended to be positioned opposite the flats of the tube. This embodiment makes it possible to define the fixing position of the elongated elements on the disc.
- the slender elements are fixed by a weld bead at the level of the flats of the disc.
- the disc has tabs extending perpendicularly to the surface of the disc at the level of the flats, the elongated elements being fixed by heat-fusion on the tabs of the disc.
- the slender element can take different forms.
- the slender element is a strip, that is to say, similar in shape to a ribbon.
- the slender element is a cable, which is thinner but nevertheless just as resistant. Indeed, the invention makes it possible to use slender elements whose width is reduced without compromising the safety of the installations.
- the slender element is formed in a metallic material, because surprisingly, the invention makes it possible to use different metallic materials for the production of the slender element without compromising the safety of the installations.

- FIG 2 is an exploded view of the fixing device of Figure 1;
- FIG 3 is a partial sectional view in perspective of the fixing device of Figure 1;
- FIG 4 is a partial sectional view of the fixing device of Figure 1;
- Figure 5 is an exploded perspective view of a device for fixing an element on a tube according to a second embodiment of the invention.
- FIG 6 is a partial sectional view in perspective of the fixing device of Figure 5.
- Figure 7 is a partial cross-sectional view of the securing device of Figure 5.
- the invention relates to a fixing device 10a-10b making it possible to mount an element 11 on one end 23 of a tube 20.
- the tube 20 is in the form of an element slender generally cylindrical. This tube 20 can be fixed, at one end not shown, to a pipe by means of a connection sleeve.
- the opposite end 23 of tube 20 is intended to receive element 11.
- Tube 20 is configured to contain a fluid such as water or gas. To do this, the tube 20 is preferably made of steel, stainless steel, copper or superchlorinated polyvinyl chloride.
- the element 11 can correspond to a sprinkler, to a manometer, or to any other element intended to be fixed on a pipe under pressure.
- This element 11 is mounted on a base 12, or equipped with a base 12, intended to be fixed on the end 23 of the tube 20.
- the tube 20 may have an end 23 with a shape adapted to the shape of the plinth 12.
- the base 12 can be used for several applications, and in particular to be attached directly to pipes, it can have a radius of curvature intended to cooperate with the radius of curvature of the pipes.
- the end 23 can be shaped with a radius of curvature equivalent to that of the base 12, as illustrated in FIGS. 1, 2 and 5.
- the tube 20 can also have a change in section in order to adapt to the dimensions of the base 12.
- the base 12 has for example a substantially planar parallelepipedic shape with a thickness of between 0.5 and 1.5 cm.
- the base 12 also has a through opening with a diameter of between 10 and 100 mm.
- the tube 20 also has a threaded portion 22 external.
- This threaded portion 22 can extend over all or part of the length of the tube 20.
- the threaded portion 22 has a discontinuous thread because flats 21 are formed over at least part of the length of the tube 20.
- the flats 21 make it possible to receive the elongated elements 15 of the fastening device 10a-10b.
- These slender elements 15 correspond, for example, to a metal strip or a strip with a width of between 0.5 and 2 cm or even a cable with a diameter of between 0.2 and 1 cm.
- the number of flats 21 and elongated elements 15 may vary without changing the invention. In the two embodiments of Figures 1 to 7, two elongated elements 15 cooperate with two diametrically opposed flats 21 on the tube 20.
- slender elements 15 make it possible to ensure a pressure of the base 12 on the end 23 of the tube 20. To do this, the slender elements 15 are fixed on the base 12 and they are distanced from the end 23 by a disc a nut 19.
- a first end 16 of the elongated elements 15 cooperates with anchor points 14 of the base 12.
- anchor points correspond to the receiving elements of the base 12 making it possible to fix the slender elements 15.
- These anchor points 14 can correspond to openings or protrusions, such as lugs.
- the anchor points 14 are formed by lugs 30 forming housings 31.
- a pin 32 disposed at the end 16 of an elongated element 15 is intended to be inserted into a housing 31 to hold the elongated element 15.
- each elongated element 15 is fixed to the disc 18 which is moved in translation away from the end 23 of the tube 20.
- the nut 19 has a thread adapted to the thread of the threaded portion 22 of the tube 20 and the nut 19 is free to rotate relative to the disc 18.
- the helical movements of the screen 19 do not cause the disc 18 to rotate but only in translation along the longitudinal axis of the tube 20 .
- the latter has an internal opening 25 whose diameter is greater than the external diameter of the tube 20 and smaller than the external radial dimensions of the nut 19.
- the outer radial dimensions of nut 19 is the dimension between opposite flats of nut 19.
- other shapes of nut may be used without changing the invention.
- the disc 18 has an outer diameter much greater than the outer radial dimensions of the nut 19.
- the outer diameter can be much smaller, or even less than or equal to the outer radial dimensions of the nut 19.
- Disc 18 and nut 19 can be made of steel or stainless steel.
- the internal opening 25 of the disc 18 preferably has flats 26 intended to be positioned facing the flats 21 of the tube 20.
- the number of flats 26 of the disc 18, as well as the number of flats 21 of the tube 20 depend on the number of elongated elements 15 intended to be fixed on the base 12.
- the disc 18 comprises tabs 27 extending perpendicular to the surface of the disc 18 at the level of the flats 26.
- the elongate elements 15 are fixed by heat-fusion on tabs 27.
- a simple weld bead 29 can be used to fix the second end 17 of each elongate element 15 to the disc 18.
- a seal 13 is positioned between the end 23 of the tube 20 and the base 12 so as to surround the opening of the base 12.
- the seal 13 is a rubber O-ring of a thickness comprised between 0.2 and 0.7 cm.
- the invention makes it possible to obtain a new method of fixing an element 11 to the end 23 of a tube 20 allowing quick and secure installation by an operator and a low production cost.
