Description

i Device for immobilizing a smooth elongate fastener in

  a hole of an element, uses of such a device and method

  manufacturing a molded element comprising such a device.

  The present invention relates to a device for immobilizing a smooth elongate fastener in a hole of an element,

  preferred uses of such a device, and to a manufacturing process

  cation of a molded element comprising such a device.

  By the European Patent Application No. 571 282,

  knows an anchoring device on the ground, using a stake, a se-

  it may be constituted for example by a terminal head or a base for a mast or pole. The sole is traversed by a passage hole for the post and comprises locking means

  comprising at least one locking piece having a portion of

  embedded in the material of the sole, and at least one claw disc

  crete which, inside the hole of the sole, protrudes from the wall of the

  hole to cooperate with the stake so as to allow, during the

  the peg through the sole, a relative movement of the

  quet in relation to the sole in the direction of depression of the stake, and

  to oppose any movement in the opposite direction.

  To correctly position the locking pieces in the sole, it is proposed in this document to use, during the molding of the sole, a lost cylindrical cladding tube lining the hole of the sole, this tube having at least one recess traversed by

  the claw of the locking piece.

  This known locking mode allows a very effective immobilization of the sole on the stake driven into the ground through the sole, but the free length of the claws of the locking pieces must be relatively low if it is desired that the tube filling the hole the sole ensures effective guiding of the sole

relative to the stake.

  In addition, the manufacturing process of the sole equipped with

  these locking means pose problems of industrialization.

  Finally, this known device is in principle only usable for soles traversed by a through hole and anchored to the ground with a stake which is driven into the ground through the sole and which has, at its end superior, a head of a larger diameter

to the diameter of the hole of the sole.

  The present invention is directed to a device for immobilizing a smooth elongated fastener in a hole of an element, a device

  which, while admitting more diverse uses, makes it possible

  known device, to give the claws pieces of ver-

  rusting, protruding into the hole of the element, a longer free length, o better immobilization efficiency, without

  assign the guidance of the element to the fastener, or reverse

  is lying. The invention also aims at an immobilizer of the type defined above allowing a simple industrialized manufacture of both the constituent parts of the device and the element equipped with

these measures.

  The invention also aims at the preferred uses of the arrangement

  immobilizer as defined above on elements capable of

  to have either a through hole or a blind hole for the

fixing bracket.

  The device according to the invention for immobilizing an or-

  The elongate, smoothly extending fastener in a hole of an element comprises at least one locking piece having an anchoring portion embedded in the element provided with a hole for receiving the fastener, and at least one discrete claw which protrudes into said hole to cooperate with said locking member, said hole having a cladding traversed by the locking piece. According to the invention, said sheath comprises, in the direction of its length, at least two spaced portions having an inner section adapted to receive and guide the fastener, and at least one intermediate portion having a

  increased inner section, the claw of the locking piece

  the sheathing at the location of the increased inner section portion.

  Thus, on the device according to the invention, the length

  of the claw of the locking piece is not determined by the inner section of the two spaced parts of the cladding ensuring the guiding of the fastener, but by an intermediate portion whose increased inner section can be chosen independently of the

  guiding function of the fastener, assumed by both parties.

  spaced apart with reduced inner section.

  In other words, on the device according to the invention, the cladding of the hole of the molded element, while assuming the two guiding functions of the element on the fastener, or conversely,

  and immobilizing the element on the fastener, or reverse

  or at least by participating in these two functions, allows

  to dissociate these two functions and, therefore, to optimize each of them.

  According to one embodiment of the invention, the cladding can consist of two half-shells connecting to each other in a plane parallel to the length of the cladding and each defining the

  half of the said parts, at least one of the two half-shells

  in the intermediate part, at least one slot for the pass-

age of a locking piece.

  Preferably, the two half-shells may comprise

  snap connection means.

  According to a preferred embodiment which is particularly suitable

  the industrialization of the manufacture of

  of the immobilizer and the elements equipped with that

  positive, the sheathing consists of at least one pair of tubular pieces

  principals each defining a section of inner section

  adapted to the section of the fastener, and a portion of section

  the two main tubular pieces are connected to each other by their parts of increased inner section. In this case, the locking piece passes through the sheathing between the two parts.

  tubular, in the connection plane of the latter.

  To be able to have, in the same element, several parts

  these locking at different heights, that is to say in different planes spaced in the longitudinal direction of the cladding, said cladding may further comprise between two tubular parts

  at least one intermediate tubular part of integral section

  increased, connecting to the increased inner section

  of the two main tubular pieces. In this case, at least one

  this lock can cross the sheath between each of the two

  main tubular parts, on the one hand, and the tubular part

  on the other hand, in each connection plane of these parts.

  On the sheathing, the tubular parts advantageously comprise

  projecting connection means passing through the plane of connection

  cord between two tubular parts and connection means

  corresponding recesses receiving said projecting means. The where

  In this case, the locking piece may advantageously comprise

  at least one hole traversed by at least one of said means for

  protruding line, for the correct positioning of the piece of

  locking with respect to the sheathing.

  In this case too, the connection means can

  advantageously consist of snap-fastening means.

  In the context of the invention, the locking pieces can

  advantageously consist of blades having a straight edge or shaped so as to provide several contact points or contact lines with the fastener, according to the profile

of the last.

  According to the process according to the invention for manufacturing a

  molded element such as a terminal head or a base for a

  water, comprising a hole lined with a sheath and at least one locking member for immobilizing this element on a stake or organ

  analogue to be driven into the ground, we assemble the pieces

  bends of the cladding according to the length of the cladding to be made,

  by interposing, in the or each connection plane of the pieces tu-

  bungs, the locking part or pieces chosen according to the profile of the stake. The cladding thus formed is then engaged with the locking piece or pieces on a centering end of the bottom of the mold and the moldable material is poured into the mold outside the cladding, thereby forming a molded element in which are drowned said

  sheathing and the anchoring parts of the locking part or parts.

  The immobilization device according to the invention can be used preferably, either for the immobilization of an element

  molded such as a base or terminal head, having a hole of

  for a picket or the like, in which case the picket is

  dark in the ground through said element, either for immobilization,

  on a peg or similar member, of a molded element such as an article

  se or a terminal head, having a blind hole for the stake, the latter then being first pressed into the ground and the molded element

  being then nested and locked on the upper end of the

  quet, or still for the immobilization of a fastener such as a smooth rod in an element that can be for example a wall or ceiling to which the device according to the invention can be incorporated, either directly during the molding of the element, or later, by

  example by sealing in a reserved hole in the wall or ceiling.

  Referring to the attached schematic drawings, we will describe

  from above, another embodiment of an immobilizer

according to the invention;

  FIG. 11 is a section of a device according to the invention;

  in use for wall mounting.

  The terminal illustrated in FIG. 1 is a cadastral or topographic terminal comprising a terminal head 1 and an anchoring stake 2

  for fixing the terminal head to the ground.

  The terminal head 1 is a solid head of molded material, for example resin concrete. The head 1 for example in the form of a truncated cone or truncated pyramid is provided with a vertical central passage hole for the stake 2, this hole comprising, in the example shown, mainly three sections 3,4,5 of different diameters, namely a lower section 3 with a diameter slightly greater than the diameter of the stake 2, connected by a shoulder 6 to an intermediate section 4 of larger diameter connecting itself by a

  shoulder 7 to an upper section 5 of even greater diameter.

  As. The anchoring stake 2 is a peg according to the French Patent No. 2 605 346 comprising a tube 8 provided at its upper end with a

  outer collar 9 which carries by means of a metal washer

  10 and a plastic washer 11 against the shoulder 7.

  At its lower end, the tube 8 encloses an end piece 12 and two auxiliary rods 13 which, crossing, pass through an orifice of the end piece 12 so that the lower ends of the two rods 13, after depression of stake 2 in the ground through the hole of the terminal head 1, can be driven with a mandrel out of the tube 8 of the stake 2 by bending in the visible manner on the

figure 1.

  The terminal head 1 is provided, in the part corresponding to the section 3 of the through hole, with a device 14 for locking the

terminal head 1 on post 2.

  As shown especially in FIGS. 2 to 4, the device for

  lock 14 comprises two main tubular pieces 15 forming

  a cladding and four locking members 16.

  Each of the two tubular pieces 15, made of a single

  plastic molded part, for example PVC,

  takes a cylindrical portion 17 connected by a truncated portion 18

  19 to a flat portion 19 of an outer flange 19 of circular inner contour and square outer contour. The flange 19 is provided

  at two opposite angles of a button 20 and at its two other angles op-

placed with a hole 21.

  The locking pieces 16 are constituted by four la-

  my rectangles each having two holes 22. For the assembly of the device 14 according to Figures 2 and 3,

  first two blades 16 are placed parallel to each other on the bridge.

  19 of a first part 15, by snapping each of them by one of its holes 22 on one of the buttons 20 of the flange 19 in question, and then placed the other two blades 16 parallel to each other. and perpendicular to the first two blades on the latter by snapping each of them by one of its holes 22 on the same buttons 20 of the first flange 19. Finally, the other piece 15 is reported by its flange 19 on both pairs of blades 16 so that its two buttons 20 pass through the other holes 22 of the four blades 16 and the holes 21 of the flange 19 of the first piece 15, and that the buttons of this other flange 19 pass through the other holes 22 of the blades 16 and

  the holes 21 of the flange 19 of the first part 15. The different parts

  these of the device 14 are thus joined and perfectly positioned relative to each other to cooperate with the stake 8 after incorporation of the device 14 to the terminal head 1 according to Figure 1. According to Figure 5, the two main tubular parts 15 each having a cylindrical portion 17, a frustoconical portion 18 and a flange 19 receive therebetween an intermediate tubular member 23 which comprises a cylindrical portion 24 having an inside diameter

  substantially equal to the maximum inside diameter of the truncated portion

  tubular pieces 15 and, at each end of the portion 24, a flange 25 corresponding to the flange 19 of the parts 15, that is to say with two buttons 20 at two opposite angles and two holes 21 at its ends.

two other opposite angles.

  The three tubular pieces, namely the two main pieces 15

  blades and the intermediate part 23 can thus be connected between

  in two parallel planes spaced in each of which it is pos-

  sible to position and position with the help of the buttons 20 of the locking pieces 16, for example as shown in FIG.

  first pieces 16 in the form of parallel blades in the upper plane.

  and two second pieces 16 in the form of parallel blades, but

  perpendicular to the first blades, in the lower plane.

  FIG. 6 illustrates another variant of immobilization,

  incorporated into a terminal head 26 of high

seized by a stake 8.

  This immobilization variant comprises two devices of

  latch 14 according to FIGS. 2 to 5, that is to say comprising each

  two tubular parts 15 with interlocking parts 16

  wedged between them, as well as an intermediate tubular part 27 constituting

  killed by a simple cylindrical tube, each end of which is

  on the cylindrical portion 17 of one of the tubular pieces 15 of

  Each device 14. The length of the part 27 can be chosen to be

  dependence on the distance sought between the two devices

locking 14.

  FIGS. 7 and 8 show a terminal head 27 equipped with a locking device 14 for a T-shaped anchoring stake 28, the terminal head 27 being closed in the upper part, that is to say 1, the post 28 must here be pushed into the ground prior to the fixing of the terminal head 27 on the upper end of the post 28 by means of the device of FIG.

lock 14.

  In order to adapt the locking device 14 to the T-profile of the post 28, the device 14 here comprises two blades 29

  and 30, namely a U-shaped blade 29 which cooperates with both lateral faces.

  opposite sides of the vertical bar and with the lower faces of the

  horizontal bar of the T-section of the post 28, and a rectangular blade 30

  which cooperates with the upper face of the horizontal bar of the

T-profile of stake 28.

  Figures 9 and 10 show a locking device 31 which is a variant of the locking device 14 of the preceding figures with particular regard to the design of the cladding

  used to hold the locking pieces.

  The locking device 31 comprises two half-parts

  pins 32 together defining a cladding comprising two cylindrical portions 33, spaced apart from one another along the axis of the cladding, and a

  intermediate portion 34 cylindrical. The parties 33 present a di-

  inner meter adapted to the diameter of the post 8 or similar anchoring element which passes through the cladding thus produced, while the part 34

  has an increased inner diameter.

  The two half-shells 32 are assembled, in a plane passing through the axis of the cladding, by means of snap-fasteners 35.

  projecting from a rim 36 that each half-shell 33 comprises

  door on one side in the zone of each portion 33, these buttons 35

  pérant with holes not shown formed in a flange 37 that each half-shell 32 has on the opposite side in the zone of each portion 33, the buttons 35 being comparable to the buttons 20 of the

previous embodiments.

  Each half-shell 32 has, in the intermediate part

  re 34 of increased inner diameter, two slots for receiving,

  after assembly of the two half-shells 32, two pieces of ver-

  rusting 38 constituted, in the illustrated example, each by a blade

  As shown, the two blades 38 are inserted into the slots

  The cladding constituted by the two half-shells 32 assembled, one from one side and the other from the opposite side. The two blades 38 thus form, in two planes offset along the axis of the device

  31, each two opposing claws cooperating with the stake 8 or orga-

  It goes without saying that the embodiments represented and de-

  have been given only as illustrative and non-limiting examples and that many modifications and variants are possible in the

framework of the invention.

  Thus, the locking pieces 16; 29, 30; 38 shaped

  rather than being arranged in planes perpendicular to the

  8, 28 or similar anchor could also be

  disposed in oblique planes with respect to the peg or

  log, in which case the flanges 19, 25 or the slots of the half-shells 32

  Figures 9 and 10 should be arranged in oblique planes.

  The shapes of these locking pieces could also be different.

  a scallop for example in an arc or a V to allow

  be at each blade to come into contact with the stake, not in a single point as in the case of a rectilinear longitudinal edge, but

  following a line or in two points.

  Apart from the anchoring of terminals and similar elements, the

  device according to the invention can find particular applications

  interesting in the ground anchoring of soles for all

  elements such as for example signs or

  poles, for example fence posts.

  Moreover, as shown in FIG. 11, the device

  of immobilization according to the invention can be used for fixing

  wall fixation, that is to say the fixation of smooth elongated organs such as

  rods or the like, in horizontal position in walls, or

  vertical position in ceilings with a view to

  ge of any elements. As shown in FIG. 11, one or more locking devices 14 according to FIGS. 1 to 8 or one or more locking devices 31 according to FIGS. 9 and 10 are incorporated in a wall 39, for example directly when the latter is molded. concrete or later, for example by sealing

  in a blind hole 41 reserved in the wall, the device 14 being des-

  adapted to receive a rod 40 or a similar elongated smooth fastening member. In the case where the device 14 is directly incorporated during molding, it can be advantageously closed at its end, side

  wall, by a cover or cap 42 preventing the penetration of

tone in the device 14.

  In the embodiment of FIG. 11, the device

  immobilisation works in the manner of a self-locking

  cante which is incorporated in the wall or ceiling and in which a rod or a similar smooth fastening member can be simply depressed 1l to be retained therein, as opposed to the usual dowels which receive screws or similar members whose insertion requires the implementation

  tools or machines such as screwdrivers, screwdrivers, etc ...

  A particular advantage of the device according to FIGS. 1 to 8 and 11 consists in the modularity, that is to say in the possibility of realigning

  with the same main elements, ie tubular

  devices 15, devices adapted to fasteners such as pi-

  quets or similar parts of various profiles, only the parts

  rust in front of, if necessary, be changed according to the profile

fasteners.
