Description

The invention relates to a method of fixing to the ground an element of urban furniture such as, for example, a telephone booth, to a method of fixing to the ground of an element of urban furniture comprising at least two feet, a device for fixing to the ground forming a foot of an item of street furniture and to a telephone booth comprising such a fixing device.

To install an element of urban furniture such as a telephone booth on the sidewalks or on the squares of a built-up area, or on the edge of a road, it is known to make a concrete base of dimensions slightly greater than the cross-section. horizontal of the cabin and fix this cabin on the concrete base by any means, for example by means of studs sealed in the concrete block or with dowels.

The external appearance of this concrete block can break the uniformity of a place, a sidewalk or a street whose covering consists of pavers or slabs of color and / or of various shapes. Thus, the installation of a telephone booth can have unattractive consequences on the urban landscape.

In addition, when a telephone booth must be installed while the floor covering is already in place, the production of the concrete block requires relatively significant civil engineering work and, in particular, the partial removal of the floor covering. Part of the coating must then be replaced until it joins the concrete block and this installation is not always possible under optimal conditions because of the geometry of the elements constituting this coating, such as, for example. example, the geometry of blocks of self-blocking pavers or slabs.

In addition, sometimes a telephone booth must be installed on sloping ground. In this case, the use of a concrete block, which must have an upper surface as horizontal as possible to allow correct installation of the cabin, leads to making a terrace or landing in this sloping ground, this terrace or landing being unattractive and resulting in the creation of an access step to the cabin likely to unbalance a user and limiting access by people with disabilities, such as, for example, people in wheelchairs.

The invention aims to solve these problems and proposes a method and a fixing device allowing the installation of an element of urban furniture without making a concrete block of large dimensions, including in the case where the ground on which must be installed this element of street furniture is sloping.

In this spirit, the invention relates to a method of fixing to the ground an element of street furniture, characterized in that it consists in fixing, in a hole in the ground, a threaded rod in a vertical position, in installing a sealing shoe on the threaded rod, adjust the height of the upper face of the sealing shoe by screwing or unscrewing the shoe on the threaded rod, immobilize the rotating shoe and inject a sealing material inside the shoe.

Thanks to the invention, the foot or feet of an element of street furniture can be put in place without major civil works, in particular without requiring the use of a large concrete block.

The invention also relates to a method of fixing to the ground an element of street furniture comprising at least two feet, characterized in that it consists in fixing, for each foot, a threaded rod in vertical position in a hole in the ground, at install a sealing shoe on the threaded rod, to adjust the height of the upper face of the shoe of each foot by rotating the shoe around the axis of the threaded rod so that the upper faces of the feet shoes belong to the same substantially horizontal plane and to immobilize the hooves in position.

In accordance with this aspect of the invention, an element of street furniture comprising several feet can be installed on a sloping ground by adjusting the height of the upper face of the shoe of each foot, this adjustment making it possible to obtain a satisfactory flatness. the bearing surface of the pillars or the walls of the street furniture element.

The invention also relates to a device for fixing to the ground forming the base of an item of street furniture which can be used with the method of the invention. It is characterized in that it comprises a threaded rod fixed in a vertical position in the ground, a sealing shoe of generally cylindrical shape, one front face of which is constituted by a veil in the center of which is drilled a tapped orifice capable of receiving the rod. threaded, the shoe being movable vertically and in rotation along the threaded rod, and a blocking element comprising means for immobilizing the shoe in rotation relative to the threaded rod.

The device of the invention makes it possible to adjust the height of the sealing shoe by rotation around the threaded rod, then to immobilize it in position by means of the locking element.

According to a first advantageous aspect of the invention, the immobilization means can comprise a lateral orifice capable of being disposed opposite a housing of the shoe of the hoof, the lateral orifice and the housing capable of receiving an indexing means such as, for example, a screw or a pin.

According to a second particularly advantageous aspect of the invention, the device comprises a means for injecting a sealing material inside the shoe, this sealing material having the essential function of contributing to the immobilization of the sealing shoe relative to the threaded rod and / or a hole in the ground.

According to another particularly advantageous aspect of the invention, the sealing shoe is open in its lower part, which allows, in particular, the sealing material injected inside the sealing shoe to flow so as to fill partially or totally the substantially cylindrical hole in which the threaded rod is fixed.

Provision may be made for the blocking element to support means for receiving and / or fixing a wall and / or a pillar of the street furniture element, so that the street furniture element can be directly fixed on this blocking element. Advantageously, the blocking element may comprise a cylindrical partition movable between a position open where it allows access to the immobilization means of the shoe and a closed position where it prevents access to these immobilization means. This cylindrical partition protects the immobilization means against the weather and against any attempt at untimely operation.

The invention finally relates to a telephone booth comprising a fixing device according to the invention.

The invention will be better understood and other advantages thereof will appear more clearly in the light of the following description of an embodiment of a device for fixing to the ground forming a foot of an item of street furniture in accordance with its principle, given solely by way of example and made with reference to the appended drawings in which:

• FIG. 1 is a front view of a double telephone booth according to the invention, mounted on the ground using the methods and the device of the invention,
• FIG. 2 is an exploded perspective view of the device for fixing to the ground forming the foot of the cabin of FIG. 1,
• FIG. 3 is a view of the device of FIG. 2 during installation,
• FIG. 4 is a view similar to FIG. 3 at a later stage of the installation of the device of FIG. 2 and
• Figure 5 is a view similar to Figure 4 when the sealing shoe is installed in a semi-buried position in the ground.

The telephone booth 1 in FIG. 1 is a double booth installed on a floor 2 having a slope of the order of 10%, so that, taking into account the fact that the width L of the booth is substantially equal to two meters, the difference in height h from the ground between the two sides of cabin 1 is approximately 20 cm. The cabin comprises a technical pole 3 through which are supplied with electric current and connected to the telephone network two public telephones not shown. This technical pole is mounted on a technical base 4 fixed in the ground.

The cabin 1 comprises several pillars, three of which, referenced 5, 6 and 7 are visible in FIG. 1. Each pillar ends in a foot formed by a fixing device, including three 11, 12 and 13 corresponding respectively to the pillars 5, 6 and 7 are visible in FIG. 1. It appears in FIG. 1 that the respective upper faces of the devices 11 to 13 must have different heights with respect to the ground in order to guarantee the good mechanical strength of the cabin.

The device 11 for fixing the cabin 1 to the ground appears more clearly in FIG. 2. It comprises a threaded rod 21, fixed by any suitable means in a vertical position in a cylindrical hole 22 made in the ground. By way of example, the threaded rod 21 may constitute the free end of a chemical anchor or of an anchor fixed by expansion in the ground. The device 11 also includes a sealing shoe 23 of generally cylindrical shape, the upper front face 23 a of which is constituted by a web 24, at the center of which is drilled a threaded orifice 25 capable of receiving the threaded rod 21. Thanks to this arrangement, the shoe 23 is movable vertically along the threaded rod 21 by screwing and / or unscrewing obtained by its rotation about the axis XX 'of the threaded rod 21.

The lower part of the sealing shoe 23 does not have a front face, so that, seen from below, the shoe 23 is a hollow tube. In other words, the shoe 23 is open in its lower part 23 b .

The device 11 also comprises a blocking element 26 of substantially cylindrical external shape, the lower front face 26 a of which comprises a central orifice 27 making it possible to engage the blocking element 26 on the threaded rod 21. The lower front face 26 a of the element 26 also comprises a lateral orifice 28 into which an indexing means such as, for example, a screw 29 can be inserted. A nut 30 can be engaged on the end of the threaded rod 21, at the inside of the blocking element 26, thanks to an opening 26 c formed in the side wall of the blocking element 26. The upper face 26 b of the blocking element 26 supports a bracket 31 comprising grooves or grooves 31 at and 31 b each capable of receiving an end chute for the walls of glass or translucent plastic material of the cabin 1. Three tapped holes 31 c make it possible to fix the pillar 5 on the upper part of the blocking element.

It follows from the above that when the shoe 23 is screwed onto the threaded rod 21, if the locking element 26 is placed on the front face 24 of the shoe 23, it is possible to accommodate the screw 29 in the lateral hole 28 and in one of two threaded housings 32 and 33 of the web 24, so that the locking element 26 and the sealing shoe 23 are fixed in rotation relative to one another. The blocking element 26 can be installed on the shoe 23 whatever the position of the latter on the rod 21 provided that the upper end of the threaded rod protrudes from the web 24 by a height greater than the thickness of the lower front face 26 a of the locking element 26 and allowing the grip of the nut 30 on the rod 21.

Given the position of the walls of glass or translucent plastic material to be arranged above the troughs 31 a and 31 b , the position of the locking element 26 around the axis XX 'of the threaded rod 21 is determined. The position of the orifice 28 and of the screw 29 is therefore also determined. The angular position of the shoe 23 around the axis XX 'is itself determined to within a half-turn insofar as the screw 29 can penetrate, at the option of the operator, into one of the two threaded housings 32 and 33. Thus, the height of the shoe 23 on the threaded rod 21 can be adjusted by screwing or unscrewing the shoe 23 to within half a turn, which, taking into account the pitch of the threaded rod 21, corresponds to a few millimeters in height , this tolerance being acceptable for the applications envisaged in street furniture.

When the screw 29 is screwed into one of the holes 32 or 33, the nut 30 is put in place and tightened on the threaded rod 21, so that it firmly holds the locking element 26 relative to the shoe 23 Thanks to the nut 30 and the screw 29, the shoe 23 is thus immobilized in rotation and in translation relative to the rod 21 and consequently, relative to the hole 22 and ground 2.

It should be noted that the function of the screw 29, which is the indexing of the angular position of the element 26 and of the shoe 23 around the axis XX ', could be achieved by other means such as, for example example, a pin, an axis or a pin fixed to the lower surface of the lower front face 26 a of the element 26.

The operation is as follows:

Referring first to Figure 3, a substantially cylindrical hole 22 having been arranged in the ground 2 and the threaded rod 21 being fixed in the hole 22, the shoe 23 is installed on the rod 21. The height of the upper face 23 a of the shoe 23 is adjusted by screwing or unscrewing the shoe on the rod 21. When the desired position is reached, the shoe 23 is immobilized in rotation by adding the locking element 26, which appears more clearly at FIG. 4. Immobilization is obtained by the combined action of the screw 29 and the nut 30.

According to a particularly advantageous aspect of the invention, the web 24 comprises two orifices 34 and 35 passing through it right through, while the lower front face 26 a of the locking element 26 comprises at least one orifice 36 positioned relative to to the lateral orifice 28, so that, when the screw 29 passes through the orifice 28 to enter one of the housings 32 or 33, the orifice 36 is disposed opposite one of the orifices 34 or 35 of the web 24. This construction allows the interior of the shoe 23 to be placed in communication with the interior of the blocking element 26 which is accessible through the opening 26 c .

In the position of FIG. 4, a sealing material such as a cement-based mortar or a resin, for example polymerizable, is injected inside the shoe 23, so that it contributes to maintaining the position of the shoe 23 relative to the rod 21 and to the hole 22, because it can spread into the bottom of the hole 22 since the shoe 23 is open in its lower part 23 b .

Thanks to the invention, the shoe 23, the locking element 26 and, consequently, the bracket 31, are firmly held in position relative to the ground and can form a foot of an item of street furniture such as a telephone booth.

It should be noted that the height of the orifice 22 used for sealing is low since it only corresponds to the reflux of the sealing material between the external face of the shoe 23 and the internal face of the orifice 22. Thus, the device of the invention can be mounted in the position of Figure 5 where the height of the orifice 22 is small compared to that of the orifice 22 in the positions of Figures 2 to 4. In practice, it is found that the device of the invention is effective while the depth of the hole 22 is limited to about 40 mm for a shoe 23 whose total height is of the order of 200 mm. Thus, in the case where, in the position of FIGS. 2 to 4, the depth of the hole 22 is of the order of 240 mm, a difference in level of 200 mm can be compensated between the feet of the telephone booth 1 by using cylindrical holes of different depths, as shown in Figure 1. The fixing device shown in Figure 5 is in the position of the device 13 of Figure 1 having a height above the ground greater than that of the device 11 .

According to an advantageous aspect of the invention, the side wall 26 c of the locking element 26 comprises a cylindrical partition 26 c 1 movable between the open position of FIG. 4 where it allows access to the means for immobilizing the shoe 23 and a closed position shown in Figure 5, where it prevents access to these immobilization means. The partition 26 c 1 therefore makes it possible to protect the immobilizing elements of the shoe 23 against the weather, to prevent dirt from accumulating inside the blocking element 26 and dissuade an unauthorized person from accessing to the screw 29 and / or to the nut 30, which makes it possible to avoid any untimely operation.

The invention finally relates to a telephone booth 1, as shown in FIG. 1, regardless of the number of telephones it contains, insofar as it comprises a fixing device as described above.

Although described with reference to a telephone booth, the invention can be applied to the fixing relative to the ground of any element of urban furniture such as a bus shelter, an advertising panel, a barrier, etc.
