DESCRIPTION

  The present invention relates to the field of urban equipment, in particular devices for delimiting and / or protecting areas, in particular access delimitation terminals, and relates to an interchangeable rigid terminal. The delimitation and / or protection of areas with limited or prohibited access, in particular to motor vehicles, in urban areas, are generally carried out by means of fixed or removable barriers or fixed or removable terminals. The barriers or the removable terminals are generally fitted by their lower ends into fixing sockets sealed in the ground and allow, by simple removal from these sockets, to free access to the protected area or site. The barriers or fixed terminals, on the other hand, are most often sealed directly at their lower part in the ground and a possibility of release

  provisional access is not possible.

  There are also small barriers permanently fixed, but foldable, and held in position by means of a lockable forestay by means of a padlock or the like or motorized bollards which can be retracted directly into the ground and allowing a passage to

authorized vehicles.

  These devices are, however, relatively expensive and time-consuming to implement and, in the event of deterioration by a violent impact, their repair is almost impossible to carry out and replacement of the entire device is

most often made necessary.

  The present invention aims to overcome these drawbacks.

  It has, in effect, for an interchangeable rigid terminal characterized in that it is essentially constituted by a terminal body, by a sealing bush in the ground and by fixing and adjusting means.

  in position of the terminal body in the socket.

  The invention will be better understood from the following description, which

  relates to preferred embodiments, given by way of nonlimiting example, and explained with reference to the appended schematic drawings, in which: FIG. 1 is an elevation view and partially in section of a terminal conforming to invention; - 2- Figure 2 is a plan view and in section, on a larger scale, along A-A of Figure 1, and Figure 3 is a view similar to that of Figure 1 of a variant

  for producing the terminal according to the invention.

  As shown more particularly, by way of example, FIG. 1 of the accompanying drawings, the interchangeable rigid terminal according to the invention is essentially constituted by a terminal body 1, by a socket 2 for sealing in the ground and by means 3 for fixing and adjusting the position of the body

terminal 1 in socket 2.

  The sleeve 2 is preferably in the form of an elongated tube 2 ', for sealing in a concrete block 4, closed at its base by a plate 5 and provided in its upper part with an outer sleeve 6 of maintenance of an upper guide ring 7. Such a sleeve 2 can be sealed extremely precisely in the ground by means of the concrete block 4 and its outer sleeve 6 is intended to allow the final coating or lining of the environment of the terminal according to the invention. Thus, after sealing in the concrete block 4, a paving or other covering trim can be placed around the outer sleeve 6, so that the terminal body 1 can

  then be placed in its final service position.

  The means 3 for fixing and adjusting the position of the terminal body 1 in the socket 2 essentially consist of at least one blocking device 8 disposed inside the terminal body 1 and acting through an opening 9 in the part lower of the terminal body 1 on the inner face of the upper guide ring 7. The locking device 8 can be in the form of an elongated part having a projecting part 8 'passing through, in the service position, the opening 9 and pressing against the internal face of the upper guide ring 7 and an operating means 10 applying the locking device 8 against the internal face of the terminal body 1 and the projecting part 8 'against the internal face of the upper guide ring 7. Thus, by tightening the device 8 against the corresponding face of the terminal body 1, its projecting part 8 'is pushed against the internal face of the upper guide ring 7 and thus tends, by reaction , push the terminal body in the opposite direction against the part

  opposite of the upper ring 7, locking in position.

  Preferably, the means 3 for fixing and adjusting the position of the terminal body 1 in the socket 2 are constituted by two blocking devices 8 arranged with an angular offset of 90. This embodiment allows more precise positioning and better tightening of the terminal body 1 in the

socket 2.

  The operating means 10 applying the locking device 8 against the internal face of the terminal body 1 and the projecting part 8 'against the internal face of the upper guide ring 7 is advantageously constituted by a clamping screw passing through the wall of the terminal body 2 and cooperating with a corresponding tapping of the locking device 8. Such a clamping screw is preferably provided with a special key operating device of the coded type

Or other.

  According to an alternative embodiment of the invention, not shown in the accompanying drawings, the operating means 10 can also be constituted in the form of a quick clamping device with threaded rod provided with a cam operating lever. Such a device first of all allows the displacement of the locking device 8 to be preset and then a final tightening of the latter by

  tilting of the operating lever, the cam of which achieves said final tightening.

  It is also possible, in accordance with another alternative embodiment of the invention not shown in the accompanying drawings, to perform the operation of the blocking device or devices by means of a device

  expansion operated from the outside by means of a threaded rod or a screw.

  In order to guarantee a more precise positioning of the terminal body 1 in the socket 2, the terminal body 1 is advantageously provided, in addition, with a positioning device 11 consisting of an elongated lever extending inside the body terminal 1 to near its base and provided at its lower end with a projecting portion 11 'passing through, in the operating position, a corresponding opening 12 of the terminal body 1 to bear against the internal face of the tube 2 ', near its base (Figures 1 and 2), an operating means (not shown) with screws, cams or expansion acting on the upper part of this

  elongated lever to apply it against the internal face of the terminal body 1.

  Advantageously, this operating means will be identical to the means 10 for actuating the locking device 8. This positioning device 11 makes it possible, in combination with the actuation of the locking device (s) 8, to perfectly adjust the verticality of the terminal body 1 per action on points

  support located at different levels in the socket 2.

  According to another characteristic of the invention, the maneuvering means of the blocking device (s) 8 and of the positioning device 11 act through corresponding bores of the terminal body 1 located in an area extending in the immediate vicinity of finished soil extending around the

outer sleeve 6.

  In accordance with another characteristic of the invention, the terminal body 1 is provided with a sliding collar 13 for protecting the operating means of the blocking and positioning devices 8 fixed in the operating position by means of pressure screws 14 Such a collar is intended, on the one hand, to protect access to the aforementioned operating means and, on the other hand, by covering these operating means, to guarantee a perfect aesthetic appearance.

the installed terminal.

  Figure 3 of the accompanying drawings shows an alternative embodiment of the invention, in which the terminal body 1 is subdivided into a part 1 'for fixing in the socket 2 and into a part 1 "of covering protruding from the ground

  surrounding and mounted on the upper end of part 1 '.

  In this embodiment, the part 1 ′ is in the form of a tubular sleeve housing the locking devices 8 and the positioning device 11. The part 1 ″ covering is preferably presented in the form of a molded part fitted on part 1 'and fixed on the latter by means of pressure screws 15 passing through the base of part 1 "and resting on the corresponding surface of the tubular sleeve forming part 1' for fixing in the sleeve, one or more pressure screws 16 can be provided in the covering part 1 "extending around the upper end of

  the part 1 'for fixing in the socket and resting on the latter.

  In the embodiment according to FIG. 3, the prior assembly of the part 1 ′ of the terminal 1 used for fixing and orienting said terminal 1 can be carried out in a particularly precise manner, the covering part 1 "

  can then be mounted quickly and easily.

  Due to the provision of one or more openings 9 in the area extending immediately below the ground level surrounding the terminal, the terminal body 1 or its part 1 ′ exhibits, at this level, a preferential fragility allowing, during a shock exceeding a predetermined intensity, a deformation of the terminal body 1 or of the part 1 '. As a result, the sealing elements, namely the sleeve 2 and its sealing block 4, do not suffer any damage and can be reused, only the terminal body 1 or the part 1 ′ requiring replacement. In the case of the embodiment according to FIG. 3, a shock against the terminal body 1 firstly causes the covering part 1 "to disengage from its fixing on the fixing part 1 'with a displacement - 5- consecutive during which the part 1 ', which is fixed more energetically in the socket 2, deforms flush with the surrounding ground. It is then enough to permanently disassemble the covering part 1 ", to remove the fixing part 1 'of the socket 2 and replace it with a new part 1', then reassemble the initial covering part 1 ". Thanks to the invention, it is possible to produce removable or interchangeable terminals, not requiring, after a relatively violent shock, that a rapid replacement of the protruding part of the terminal, the sealed part remaining permanently and can be reused. When using terminals in two interlocking elements, namely a fixing element and a el ment covering only the fastener will be replaced. As a result, interventions to replace damaged terminals or to replace terminals of a certain type with terminals of another type can be carried out very quickly and without requiring heavy and bulky intervention equipment or repair work. genius

civil.

  Of course, the invention is not limited to the embodiments described and shown in the accompanying drawings. Modifications remain possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without thereby departing from the scope of

protection of the invention.
