Description

The present invention relates to a device for fixing

  an accessory, for example a wall spotlight, on a swimming pool wall intended to be immersed. There are various types of inground pools, which are distinguished by their manufacturing process. Two main types of manufacturing processes are currently used. A first method consists in digging a hole, in coating the walls of the hole with building materials such as for example concrete plates, bricks or metal plates. The walls are then covered by a coating layer

  waterproof, commonly called "liner".

  Another method consists in placing a shell of synthetic material, for example polyester, in the hole made. The shell is waterproof and no coating

is not necessary.

  When it is a question of fixing an accessory, such as for example a projector, at the level of the interior wall of the swimming pool, that intended to be in contact with water, the method of fixing depends on the manufacturing method of the swimming pool . In the case of a masonry swimming pool covered with a liner, it is possible to fix the accessory directly on the wall of the swimming pool, while with a polyester shell, the shell is sandwiched between the accessory placed at the interior of the pool and a

  fixing piece placed outside the pool.

  For the same accessory, two separate fixing methods must then be provided, depending on whether it is intended to be mounted in a masonry swimming pool or a swimming pool comprising a shell and therefore two separate fixing devices. In all cases, the fact that the accessory is submerged requires carrying out a

  tightness at this level.

  The object of the invention is therefore to provide a device allowing the attachment of an accessory to a wall of a swimming pool, which can be used both for fixing the accessory to a wall of a masonry swimming pool and to a hull. polyester. To this end, the device allowing the attachment of an accessory to a swimming pool wall intended to be immersed which it proposes comprises a flange intended to follow the shape of the wall of the swimming pool and to receive the accessory and / or its possible support, as well as a tubular part extending essentially on one side of the flange, opening at its two ends in order to allow the supply of the accessory, for example in

electric energy.

  This device can take place both on a wall of a masonry pool and on that of a shell

made of synthetic material.

  In the case of a masonry swimming pool, the tubular part of the device is sealed in the wall and the flange conforms to the face of the wall. It then allows

mounting an accessory.

  In the case of a swimming pool comprising a plastic shell, the device can be fixed using a counter-flange which faces the flange on the opposite side of the shell and the flange then serves for the fixing of the accessory. It is also possible to screw the flange

  on the hull, which removes the counter flange.

  In an advantageous embodiment, the flange is a flat flange comprising two series of holes, one for fixing the accessory and / or its possible support on one face of the flange and the other for fixing a

  counter flange on the other side of the flange.

  To facilitate the fixing or sealing of the device in a masonry wall, the latter preferably comprises a second tubular part, surrounding the first. In this case, the two tubular parts are advantageously coaxial and are connected by a ring substantially perpendicular to the axes of the tubular parts. When the device comprises two tubular parts, the end of the second tubular part is advantageously threaded on the side opposite the flange. The device can thus be mounted by screwing in a

  part sealed in the masonry wall.

  In the latter case, to facilitate screwing, the end of the first tubular part preferably has a non-circular peripheral surface on the side of the flange, so that it can be driven in rotation.

by a tool.

  The present invention also relates to a pool projector, comprising a bulb mounted in a housing, a power cable passing through the housing and fixing lugs, and further provided with a device such

as described above.

  The housing of this projector is advantageously fixed to the fixing lugs by a system

bayonet type.

  The projector preferably comprises, for mounting on a masonry wall, two seals intended to seal on the one hand between the fixing device according to the invention and a layer of waterproof coating for a swimming pool, or liner, And on the other hand

  between the liner and the fixing lugs.

  For mounting on a swimming pool with a shell, the swimming pool floodlight preferably includes

a mounting flange.

  In any case, the invention will be well understood at

  using the following description, with reference to the drawing

  diagram attached, showing by way of nonlimiting example a preferred embodiment of

the invention.

  Figure 1 is an exploded side view of a wall lamp comprising a fixing device according to the invention, Figure 2 is a side view of a fixing device according to the invention and of a support fixed on it in the mounted position, Figure 3 is a sectional view on an enlarged scale compared to the previous figures of a fixing device according to the invention, and Figure 4 is a front view along the arrow F of

Figure 3.

  Figure 1 shows various components constituting a projector and allowing it to be fixed on a wall 2 of

  masonry pool intended to be immersed.

  The headlamp comprises in a known manner a box 4 inside which is mounted a socket in which there is a bulb (not shown), by

example a halogen bulb.

  This box 4 is mounted on a support 6 comprising a base 8 and fixing lugs 10 connected to the base

8 by link arms 12.

  The base 8 of the support 6 is of annular circular shape. The fixing lugs 10 are in a plane parallel to that containing the base 8. The arms 12 each connect a fixing lug 10 to the base 8. These arms 12 are attached to the outer periphery of the annular circular base 8. The assembly formed by an arm 12 and a fixing lug 10 has substantially the shape

with a folded tab.

  The base 8, the arms 12 and the fixing lugs are advantageously made in a single molded part

made of synthetic material.

  The housing 4 is fixed to the support 6 by a bayonet locking system 14. These

  the latter are shown in dotted lines in FIG. 1.

  FIG. 2 does not represent a housing 4 for the sake of clarity, but an identical or different housing 4 could be adapted on the support 6 shown in this

  figure and which is identical to that of figure 1.

  The support 6 is fixed to a fixing device 16 according to the invention, either directly (FIG. 2), or indirectly, that is to say with

  interposition of elements as shown in Figure 1.

  Figures 3 and 4 show in more detail a fixing device 16 according to the invention. They represent in particular a flange 18, a first tubular part 20, a second tubular part 22 and a ring 24 allowing the connection between the two tubular parts

and 22.

  The flange 18 is of circular annular planar shape so as to match the shape of the wall of the

  pool on which it is intended to take place.

  It presents two series of holes. A first series of four holes 26 placed on the same circle is provided for fixing the support 6. The holes are here blind holes and therefore a boss 28 appears on the side of the flange 18 opposite the side intended to receive

support 6.

  To simplify the description which follows, the face

  respectively the side intended to receive the support 6 and which are on the right in FIG. 3 will be called subsequently face, respectively side, front. In contrast, the other side will be called the back side and the back of a part will be the area of the part located at

left in figure 3.

  A second series of eight holes 30 is made at the periphery of the flange for fixing

  of a part, for example a counter flange 32 (Figure 2).

  These holes are through holes. They find themselves

  also all eight on the same circle.

  The first tubular part 20 is arranged coaxially with the flange 18 on an axis 34. It extends

  backwards from the plane containing the flange 18.

  It is intended to let pass a power supply cable 36 for the projector. It has on its inner surface, at each of its ends, a thread. It opens at its two ends, providing a through passage for a cable

36 or whatever.

  The front thread can for example be used to screw a cable gland (not shown) in the first tubular part 20. In this way, the cable sheath

  36 located at the rear of the cable gland remains dry.

  The rear thread can be used to make a connection with a sheath leading the cable 36 from a connection box (not shown) to the device

of fixation.

  The second tubular part 22 is also of axis 34. It surrounds the first tubular part 20. Its outer surface is threaded at its rear end. This tubular part 22 is used for fixing the fixing device 16 in the wall 2. This device 16 can be simply sealed in a wall. In this case, the thread is of no use. In another case, the fixing device 16 can be screwed into a wall passage 38 using the thread of the second tubular part 22. A wall passage 38 is a part known to those skilled in the art, which is set up during the construction of a swimming pool, during the execution of the structural work of a masonry swimming pool, to allow the installation of equipment, generally a discharge nozzle. Such a wall crossing 38 can cleverly be used with a device according to the invention for mounting a projector. The thread of the second tubular part is then screwed into the wall passage 38, at the place generally provided for

receive a discharge nozzle.

  The two tubular parts 20 and 22 are connected by the ring 24. The latter simply constitutes a wall perpendicular to the axis 34 and connecting the two tubular parts. This ring 24 is advantageously arranged in the middle of the tubular parts 20, 22. This makes it possible to have a device which is more mechanically resistant, but also makes it possible to make the front end of the first tubular part 20 accessible. The latter then advantageously has a non-circular peripheral surface, allowing cooperation with a tool. In the preferred embodiment shown in the figures, this end has an outer surface having a hexagonal section. Thus, when the device 16 is screwed into a wall passage 38, it is possible to ensure the tightening of the device 16 in the

  wall crossing 38 using an appropriate key.

  Preferably, this fixing device is made by molding in synthetic material and is of a

in one piece.

  The mounting of a projector can be carried out according to the invention on a masonry swimming pool as well as on a swimming pool comprising a shell of synthetic material. The advantage of the projector according to the invention is that by using substantially the same parts, it is possible to fix it either on a masonry pool wall, or on a pool wall made of synthetic material. In the case of a masonry swimming pool (Figure 1), the fixing device 16 is fixed in the wall 2 when the latter is produced. We can either directly seal this device 16 in the wall, or seal a wall bushing 38 and then come and screw the device in the wall bushing. If the device 16 is directly sealed in the wall 2 (case not shown), the second tubular part 22 is preferably long enough to pass through the wall 2. The flange 18 of the device is located

  on the side corresponding to the interior of the pool.

  A seal 40 is then bonded to the flange 18, on its front face, at the level of the first series of holes 26. The swimming pool is then covered with a coating making it possible to ensure its sealing. This coating is commonly called a liner. He is represented

  in a dashed line in FIG. 1 and bears the reference 42.

  A second seal 44 takes place on the other side of the liner, facing the first seal 40. The support 6 is then screwed onto the fixing device 16. The screws can either pass through the liner and the seals, 44, or holes can be made before passing the screws. A cable gland is optionally mounted in the first tubular part 20. Finally, the housing 4 of the projector is mounted on its support 6 by passing the cable 36 inside the first part.

tubular 20.

  When the pool has a plastic shell 46, the assembly is slightly different but

  it implements almost the same parts.

  Indeed, the fixing device 16 is put in place on the shell 46. A passage has been made before in the shell 46 to allow the positioning of the device 16. To maintain the device 16, a counter-flange 32 comes to face the flange 18 on the other side of the shell 46. The flange 18 is then inside the pool while the counter-flange 32 is outside the shell 46. Fixing screws can connect the flange 18 and counter-flange 32. These screws then pass through the holes 30 in the flange 18. A seal (not shown) in foam or silicone can perfect the seal inside the shell 46. Then simply set up the support 6 using screws and holes 26, possibly screw a cable gland in the first tubular part 20 and mount the housing 4 of the projector by passing the cable 36 in the passage planned at this

  effect in the fixing device 16.

  It goes without saying that the invention is not limited to the preferred embodiment described above by way of nonlimiting example; on the contrary, she embraces

all variants.

  Thus, the fixing device does not necessarily have two tubular parts. The outer tubular part could be removed. The inner tubular part could then possibly be of a larger diameter and perform the functions of maintaining the device in a wall. This outer tubular part could also be replaced by anchor rods. The shape of this device, the presence or absence of threads, threads and other surfaces of polygonal section can vary without departing from the framework

of the invention.

  The fixing device which allows you to cleverly mount an accessory on a swimming pool wall, can be used in combination with other parts

  separate from the support and the housing described.

  The wall connecting the two tubular parts could be replaced by a ring or an elastic sleeve ensuring a tight connection between these two parts. The device would then be in three separate parts.
