Description

[0001] The invention relates to a swimming pool grating, swimming pool equipment and a method for installing these.

[0002] The field of the invention relates to recreational or bathing swimming pools.

[0003] It is known that such a grating can be installed above a pool cover reel. The reel allows the cover to be unfurled on the surface of the pool water to prevent debris from contaminating the water and to prevent people from accidentally falling into the pool. The cover also provides thermal insulation for the pool and reduces heat loss.

[0004] The reel typically consists of a reel shaft submerged in the pool water, housed in a casing located near the swimming area. A submerged partition wall separates the reel shaft from the pool, allowing water and the cover to pass through. The reel shaft can be driven by a motor to unroll the cover onto the pool's surface or to retract the cover onto the shaft, freeing the pool's surface.

[0005] The grating must be installed above the reel shaft, to protect it and prevent people from accessing it.

[0006] By doing so, once the grating is installed and the pool is filled with water, people should be able to walk on the grating and see it.

[0007] One of the problems with this grating is its weight.

[0008] Existing gratings, including those with a profile, have a high material cost for a fixed appearance. These costs limit the possible appearances and finishes of the grating due to the material expense.

[0009] One objective of the invention is to obtain a swimming pool grating that allows for easy changes in appearance while overcoming the disadvantages mentioned above.

[0010] To that end, a first object of the invention is a grating according to claim 1.

[0011] The invention allows for changing the appearance without having to replace the entire grating, thus reducing material costs. Indeed, any one of several decorative profiles can be mounted on the same main profile, resulting in savings on the main profile itself.

[0012] The decorative profile can therefore be easily mounted and changed by the user to adapt its visual effect to the aesthetic desired by the user.

[0013] The decorative profile can be interchanged from a selection of profiles with different appearances, materials, and / or surface finishes. This allows the user to choose the desired visual appearance of the decorative profile attached to the main profile. For example, the decorative profile can be chosen to match the color of the pool edges or other pool elements.

[0014] Claims 2 to 11 relate to embodiments of the grating.

[0015] A second object of the invention is equipment according to claim 12.

[0016] A third object of the invention is equipment according to claim 13.

[0017] Claim 14 relates to an embodiment of the equipment.

[0018] A fourth object of the invention is a method for installing the equipment according to claim 15.

[0019] The invention will be better understood upon reading the following description, given solely as a non-limiting example with reference to the figures below of the attached drawings.

[0020] We describe in more detail below with reference to figures 1 to 13 examples 1a, 1b, 1c of grating 1 according to the invention.

[0021] Grating 1 is a swimming pool grating, as indicated above.

[0022] The grating 1 has an upper surface 2 and an outer surface and a lower surface 3. The grating 1 has one or more rails 10, such as for example four rails 10 at Figures 10 to 12 Each rail 10 is oblong, having a greater length along a horizontal longitudinal direction Y extending from back to front than along a transverse horizontal direction X extending from left to right. In the figures, the vertical direction Z is oriented from bottom to top.

[0023] In the case where the grating 1 has several rails 10, the rails 10 are located side by side along the horizontal transverse direction X and are fixed to one (or more) cross member 7 located under the main profiles 11 of the rails 10 and extending along the horizontal transverse direction X. The cross member 7 may be flat in the plane of the X and Y directions. The cross member 7 may be metallic. The cross member 7 may be formed by a reinforcing plate. Decorative profile

[0024] As represented at figures 1 to 5The rail 10, or each of the rails 10, comprises a main profile 11 and a decorative profile 12, which is removably attached to the main profile 11. The rail 10 includes removable connecting means for attaching the decorative profile 12 to the main profile 11 and for detaching the decorative profile 12 from the main profile 11. The main profile 11 has a constant cross-section in planes perpendicular to the horizontal longitudinal direction Y. The main profile 11 has one or more cavities 119 between its upper part 126 and its lower surface 3. The upper part 126 may, for example, be flat in the plane of the X and Y directions. The lower surface 3 may, for example, be flat in the plane of the X and Y directions. The decorative profile 12 has a constant cross-section in planes perpendicular to the horizontal longitudinal direction Y.

[0025] The decorative profile 12 covers the main profile 11 on the top, right and left.

[0026] The decorative profile 12 comprises, from left to right, a left side 123, a central section 121, and a right side 122, which are connected to each other. The left side 123 can be connected to the central section 121 by a right-hand curved elbow 127. The right side 122 can be connected to the central section 121 by a left-hand curved elbow 128. The central section 121 can contain a plane extending along the X and Y directions. The left side 123 can contain a plane extending along the X and Z directions. The right side 122 can contain a plane extending along the X and Z directions.

[0027] The upper surface 2 of the grating 1 lies at least partially or entirely on the central portion 121 of the decorative profile 12. The upper surface 2 located on the central portion 121 of the decorative profile 12 forms a decorative surface. The right side 122 and the left side 123 are situated on either side of the central portion 121 and below the level of the upper surface 2. The width of the central portion 121 along the horizontal transverse direction X is greater than the height of the left side 123 below the central portion 121 along the vertical direction Z. The width of the central portion 121 along the horizontal transverse direction X is greater than the height of the right side 122 below the central portion 121 along the vertical direction Z. The decorative profile 12 may be in the shape of an inverted U, having the central portion 121, the right side 122, and the left side 123.

[0028] The right-hand side 122 has, in its inner part facing left, a first clipping member 124, facing left. The left-hand side 123 has, in its inner part facing right, a second clipping member 125, facing right and therefore facing the first clipping member 124.

[0029] The decorative profile 12 has a mounting position M, shown in figures 4 , 9 , 10 , 11 , 12 , 14 , 15 , 16 , 17A, 17B, 17C, 17D , 17E, 17F , 18 , 19 , 20A, 20B , 21, 22 , 24A, 24B , 25A, 25B, 26A and 26Bin which the decorative profile 12 is fixed against the main profile 11. In the mounting position M, the central part 121 of the decorative profile 12 is located against the upper part 126 of the main profile 11, the decorative profile 12 being located between the right side 122 and the left side 123. In the mounting position M, the first clipping member 124 is constrained and wedged against a first part 114 of the main profile 11. In the mounting position M, the second clipping member 125 is constrained and wedged against a second part 115 of the main profile 11. The first part 114 of the main profile 11 and the second part 115 of the main profile 11 are located on either side of the upper part 126 of the main profile 11 and below the level of the upper part 126 of the main profile 11. The profile 12 The decorative element can thus be clipped and unclipped from the main profile 11.The material of the decorative profile 12 has a certain aptitude for bending to return to its original shape so that it can be clipped into the mounting position on the main profile 11 and so that it can be unclipped.

[0030] Once a first decorative profile 12 is clipped onto the main profile 11, the user can unclip this first decorative profile 12 to clip a second decorative profile 12 onto the same main profile 11. This second decorative profile 12 has a different appearance on its upper surface 2 than the first decorative profile 12. Thus, a set of several decorative profiles 12 can be provided, each with upper surfaces that have different appearances and / or colors and / or materials and / or surface finishes and / or different reliefs. Each decorative profile 12 in the set can be clipped onto the same main profile 11. This set of decorative profiles 12 and the main profile 11 together form a kit for assembling the equipment. Alternatively, only one decorative profile 12 can be clipped onto the same main profile 11 at a time.It could also be envisaged that several decorative profiles 12 could be clipped one after the other along the horizontal longitudinal direction Y on the same main profile 11.

[0031] The decorative profile 12 can be made of a synthetic material, such as polycarbonate, PVC, PMMA, or another material. Alternatively, the decorative profile 12 can be made of metal (such as aluminum) or another material.

[0032] The main profile 11 may be made of a synthetic material, such as polycarbonate, PVC, PMMA, or another material. Alternatively, the main profile 11 may be metallic (such as aluminum) or made of another material.

[0033] In the first example 1a of the grating 1 to figures 1 to 4Prominent ribs 21 extending along the horizontal longitudinal direction Y and grooves 22 extending along the horizontal longitudinal direction Y may be provided on the upper surface 2 of a decorative profile 12. These protruding ribs 21 alternate with the grooves 22 in the X direction. These protruding ribs 21 and grooves 22 thus form a non-slip upper surface 2 and allow a user to reduce the risk of slipping on the surface 2.

[0034] In the second example 1b of the grating 1 to Figures 1 , 5 and 6 A flat upper surface 2 of a decorative profile 12 may be provided. The upper layer of surface 2 may consist of a flat film bonded to a synthetic material or a flat layer of lamination bonded to a synthetic material, for example to imitate a material such as wood.

[0035] In the third example 1c of the grating 1 to Figures 1 , 7 , 8 And 9 Projecting ribs 21 extending along the horizontal longitudinal direction Y and grooves 22 extending along the horizontal longitudinal direction Y may be provided on the upper surface 2 of a decorative profile 12. Several groups 210a, 210b, 210c of these projecting ribs 21 alternating with these grooves 22 along the X direction are separated from each other by flat portions 211 along the X direction. These projecting ribs 21 and grooves 22 thus form a non-slip upper surface 2 and allow a user to reduce the risk of slipping on the surface 2.

[0036] According to one embodiment of the invention, to figures 1 to 13The first clipping member 124 has a first lug 1240 (or a male member). The first part 114 of the main profile 11 has a first corner 1140 projecting downwards and to the right, the first lug 1240 being constrained and wedged against the first corner 1140 in the mounting position M. The second clipping member 125 has a second lug 1250 (or a male member). The second part 115 of the main profile 11 has a second corner 1150 projecting downwards and to the left, the second lug 1250 being constrained and wedged against the second corner 1150 in the mounting position M. The first lug 1240 is oriented towards the second lug 1250. The first lug 1240 is oriented to the left and upwards. The second lug 1250 is turned to the right and upwards. In the M mounting position, the first lug 1240 is pressed against the bottom of the first corner 1140 to the left.In the M mounting position, the second lug 1250 is pressed against the bottom of the second corner 1150 to the right.

[0037] According to one embodiment of the invention, to figures 1 to 13 The first part 114 is connected to a side wall 1141, which is located to the right of the upper part 126 and which can, for example, be flat and form an obtuse angle with the upper part 126. The second part 115 is connected to a side wall 1151, which is located to the left of the upper part 126 and which can, for example, be flat and form an obtuse angle with the upper part 126. This facilitates the insertion of the main profile 11 into the decorative profile 12 up to the mounting position M during clipping.

[0038] The first part 114 of the main profile 11 is connected to the lower surface 3, for example, by a flat wall 34 forming an obtuse angle with the lower surface 3. The second part 115 of the main profile 11 is connected to the lower surface 3, for example, by a flat wall 35 forming an obtuse angle with the lower surface 3. The side wall 1141 is connected to the upper part 126, for example, by a curved elbow 1142 on the upper right. The side wall 1151 is connected to the upper part 126, for example, by a curved elbow 1152 on the upper left. The first corner 1140 forms, for example, an obtuse angle from the right side wall 1141 to the oblique flat wall 34. The second corner 1150 forms, for example, an obtuse angle from the left side wall 1151 to the oblique flat wall 35.

[0039] In another embodiment of the invention, not shown, the first clipping member 124 may have a first left-facing groove (or a recess or a female member), and the first portion 114 of the main profile 11 may have a first right-facing lug (or a male member), the first lug being constrained and locked into the first groove in the mounting position M. The second clipping member 125 may have a second right-facing groove (or a recess or a female member), and the second portion 115 of the main profile 11 may have a second left-facing lug (or a male member), the second lug being constrained and locked into the second groove in the mounting position M.

[0040] According to one embodiment of the invention, the rail 10 or each of the rails 10 has at least one gap allowing water to pass through the main profile 11 and / or between the main profile 11 and the decorative profile 12. The interior space of each rail 10 and of the grating 1 can thus be filled with water.

[0041] To figures 1 to 13The decorative profile 12 may include, beneath a portion of its upper surface 2, namely a portion of the central part 121, a wedge 130 (or several wedges 130 spaced apart along the X direction) extending along the horizontal longitudinal direction Y and downwards. Correspondingly, the upper portion 126 of the main profile 11 includes one (or more) recess 131 extending along the horizontal longitudinal direction Y and downwards, each recess 131 serving to house a wedge 130 in the mounting position M. The wedge 130 (or wedges) serves to reinforce the decorative profile 12, preventing it from sagging.

[0042] In the first example 1a of the grating 1 to figures 1 to 4 and in the second example 1b of the grating 1 to Figures 1 , 5 and 6 , each wedge 130 has a closed shape downwards and can be rectangular with the central part 121.

[0043] In the third example 1c of the grating 1 to Figures 1 , 7 , 8 And 9 , each wedge 130 has an open shape downwards and can be formed of two vertical walls 130a and 130b descending downwards and spaced apart from each other along the X direction.

[0044] To figures 1 to 13, the decorative profile 12 may include under the upper surface 2, namely under the central part 121 and / or to the right of the left flank 123 and / or to the left of the right flank 122 one (or more) support rib 129 extending along the horizontal longitudinal direction Y and descending downwards. The decorative profile 12 is thus supported against the main profile 11 in the mounting position M solely by the support rib(s) 129, as well as by the first clip element 124 and the second clip element 125, and possibly by the shim(s) 130. The remainder of the lower surface 129' of the decorative profile 12, at a distance from the support rib(s) 129 and at a distance from the clip elements 124, 125, is thus set back by a non-zero distance from the main profile 11. This limits the contact area between the decorative profile 12 and the main profile 11, which facilitates the possible unclipping of the decorative profile 12.

[0045] The main profile 11 can serve as a central support for various functions.

[0046] In the first case, as represented in Figures 1 to 29B , the elements described below can be provided on the grating 1 having the elements described above (including in particular the decorative profile 12 and the clipping devices).

[0047] In a second case, not represented at Figures 1 to 29BThe elements described below can be provided on a grating that does not have the elements described above (therefore, in particular, lacking the decorative profile 12 and the clipping mechanisms). In this second case, the elements described below can be provided, for example, on a grating with a main profile 11, which is a single piece with both the upper and outer surface 2 and the lower surface 3, and therefore, in particular, lacking the decorative profile 12 and the clipping mechanisms. In this second case, the elements described below can be provided, in another example, on a grating that, instead of the main profile 11, has a solid piece with both the upper and outer surface 2 and the lower surface 3, and therefore, in particular, lacking the decorative profile 12.Thus, in this second case, the elements described below can be provided for example with a tileable grating; or with a stone grating, or with a weldable grating. Mounting brackets

[0048] According to an embodiment of the invention, as illustrated in figures 11 to 17F , the grating 1 or the main profile 11 of the rail 10 or of at least one of the rails 10 has a lower surface 3 comprising or carrying means 4 for fixing.

[0049] According to an embodiment of the invention, as illustrated in figures 11 to 17FThe fastening means 4 comprise one (or more) front tab 41, which is fixed under the rail 10 or under at least one 101a of the rails 10, and one (or more) rear tab 42, which is fixed under the rail 10 or under at least one 101b of the rails 10. The front tab 41 projects forward and downward. The rear tab 42 projects backward and downward. The rail 101a may be the same as the rail 101b or may be different from the rail 101b.

[0050] The grating 1 can thus be fixed by the cooperation of the front tab 41 and the rear tab 42 on a front beam 100 and on a rear beam 200 in a fixing position F in a structure 2000 for swimming pool.

[0051] Because the front leg 41 and the rear leg 42 are oriented away from each other along the Y direction, namely that the front leg 41 extends forward in the direction of Y and the rear leg 42 extends backward in the opposite direction of Y, the grating 1 can be placed in the fixing position F on the beams 100 and 200 by tilting the grating 1 backward ( Figures 17A and 17B ) then forward ( Figures 17C, 17D , 17E and 17F) to insert the rear tab 42 into the rear beam 200 and then to insert the front tab 41 into the front beam. This allows the grating 1 to be held on the beams 100 and 200 in the fixing position F with less force exerted on the tabs 41 and 42, thus reducing the risk of breakage. The tabs can then be held in opposite directions in the horizontal transverse direction X within the beams 100 and 200. This simplifies the installation of the grating 1. It also eliminates the need to ballast the grating 1 and avoids the use of grating 1 locking hooks on the beams.

[0052] According to an embodiment of the invention, as illustrated in figures 11 to 17FThe first and second rails are formed by a single rail 101a, with the front lug 41 positioned at a distance from the rear lug 42 beneath the rail 101a. Another front lug 41 and another rear lug 42 may be fixed beneath another rail 101b. For example, a front lug 41 and a rear lug 42 may be fixed beneath the leftmost rail 101a, and another front lug 41 and another rear lug 42 may be fixed beneath the rightmost rail 101b, as illustrated in the diagrams. Figure 10 And 11 In addition to the rails 101a and 101b, one or more other rails 10 may be provided, which do not have the lugs 41, 42. For example, four rails 10 may be provided at Figures 10 to 12 .

[0053] In an alternative not shown in the above embodiment, the rails 10 may only include the 2 rails 101a and 101b in the grating 1.

[0054] In a variant not shown in the embodiment above, several rails 101a and / or several rails 101b may be provided in the grating 1. Swimming pool equipment and structure

[0055] To figures 17A, 17B, 17C, 17D , 17E and 17F An example of the 2000 swimming pool structure is shown. The 2000 swimming pool structure can include the grating 1, a first front beam 100 for placing the grating 1 on top in a fixing position F and a second rear beam 200 for placing the grating 1 on top in the fixing position F.

[0056] To figures 11 to 17F , the 1000 pool equipment, consisting of the grating 1, the first front beam 100 and the second rear beam 200, is intended to be fixed above a shaft A of a pool cover reel, as described above, to be fitted to the pool.

[0057] Structure 2000 comprises a right wall and a left wall, which are located at least partially opposite each other. The first front beam 100 and the second rear beam 200 are fixed between these walls once installed, as described below. The longest horizontal dimension (length) of the first front beam 100 extends along the transverse horizontal direction X between the right wall and the left wall. The longest horizontal dimension (length) of the second rear beam 200 extends along the transverse horizontal direction X between the right wall and the left wall.

[0058] Shaft A can be rotated by a motor in one direction and the other around an axis extending along the horizontal transverse direction X between the right wall and the left wall, to wind the cover around shaft A and to unwind the cover relative to shaft A into a horizontal deployment position in basin B. The pool cover can be formed of slats hinged one after the other, the rear slat of which is fixed to the periphery of shaft A.

[0059] Structure 2000 comprises a front vertical wall 2001 and a rear vertical wall 2002, which, along with the right and left walls, define the enclosure C in the bottom of which the shaft A of the pool cover reel is mounted. The front vertical wall 2001 can be a front wall or any other type of wall. The rear vertical wall 2002 can be a back wall or any other type of wall.

[0060] Swimming pool B can be located behind the rear vertical wall (2002). figures 17A, 17B, 17C, 17D , 17E and 17F , in which case the rear vertical wall 2002 is a separation wall located between basin B and the caisson and is submerged by water, the pool cover being able to pass over this separation wall and the front vertical wall 2001 is higher than the rear vertical wall 2002 to contain the pool water.

[0061] Of course, as an alternative, the B swimming pool could be located in front of the front vertical wall 2001, in which case the front vertical wall 2001 is a separation wall located between the B pool and the caisson and is submerged by the water, the pool cover being able to pass over this separation wall and the rear vertical wall 2002 is higher than the front vertical wall 2001 to contain the pool water.

[0062] Of course, in the equipment 1000, several gratings 1 could be arranged one after the other along the horizontal transverse direction X in the position F of fixing on the same front beam 100 and on the same rear beam 200. Of course, one or more equipment 1000 each consisting of the grating 1, the first front beam 100 and the second rear beam 200 could be provided in the structure 2000 for swimming pool.

[0063] The embodiments of equipment 1000 are described below, as illustrated in the figures 11 to 17F .

[0064] According to one embodiment of the equipment 1000, the first front beam 100 has a first groove 101 turned upwards, to allow the insertion into it of the front leg 41, in order to fix the grating 1 to the beams 100 and 200.

[0065] In the first groove 101, namely on the rear surface of a front wall 107 delimiting the first groove 101, there is a first stop 102, which projects rearward. The first stop 102 has a downward-facing horizontal edge 109. The first front beam 100 has a first bottom wall 103 delimiting the first groove 101 and having a first wall portion 105 inclined rearward and downward, which is located vertically below the first stop 102. The first stop 102 defines, with respect to the first wall portion 105, a first rearward-facing opening 104 and has a first non-zero vertical distance D1 along the vertical Z direction relative to the first wall portion 105. The front leg 41 has a first front end portion 411 having a first non-zero height H1 along the vertical Z direction. The first vertical distance D1 is greater than the first height H1.

[0066] The first front end part 411 of the front leg 41 is inserted into the first opening 104 of the first front beam 100 under the first stop 102 in the fixing position F of the Figures 15 And 17F . The first front end part 411 of the front leg 41 can be in contact against the first stop 102 in the fixing position F or can be at a non-zero vertical distance below the first stop 102 in the fixing position F.

[0067] The second rear beam 200 has a second groove 201 facing upwards, to allow the insertion of the rear bracket 42, in order to fix the grating 1 to the beams 100 and 200. A rear edge of the second groove 201 is formed by a second stop 202, which projects forwards. The second beam 200 has a second bottom wall 203 delimiting the second groove 201 and having a second wall portion 205, which is located vertically below the second stop 202. The second stop 202 defines, with respect to the second wall portion 205, a second forward-facing opening 204 and has a second non-zero vertical distance D2 along the vertical Z direction relative to the second wall portion 205. The rear bracket 42 has a second rear end portion 421 having a second non-zero height H2 along the vertical Z direction. The second vertical distance D2 is greater than the second height H2.The second rear end part 421 can, for example, be in the form of a horizontal blade extending rearward to the . figures 16 , 17A , 17C And 17E . The second rear end part 421 may, for example, be of lesser height than the first front end part 411 of the front leg 41 and its lower front end 412, along the vertical direction Z.

[0068] The second rear end part 421 of the rear leg 42 is inserted into the second opening 204 of the second rear beam 200 under the second stop 202 in the fixing position F of the figures 16 And 17E . The second rear end part 421 of the rear leg 42 can be in contact against the second stop 202 in the fixing position F or can be at a non-zero vertical distance below the second stop 202 in the fixing position F.

[0069] According to one embodiment of the equipment 1000, the horizontal distance between the first front end portion 411 of the front leg 41 and the second rear end portion 421 of the rear leg 42 along the horizontal longitudinal direction Y is less than or equal to the horizontal distance between the front bottom 106 of the opening 104 and the rear bottom 206 of the opening 204. The horizontal distance between the first front end portion 411 of the front leg 41 and the second rear end portion 421 of the rear leg 42 along the horizontal longitudinal direction Y is greater than the horizontal distance between the first stop 102 and the second stop 202.

[0070] According to one embodiment of the equipment 1000, the first front end part 411 is at a non-zero vertical distance from the first wall part 105 in the fixing position F.

[0071] According to one embodiment of the equipment 1000, the second rear end part 421 is at a non-zero vertical distance from the second wall part 205 in the fixing position F.

[0072] The 1000 fitting allows for play along the horizontal longitudinal Y direction and the vertical Z direction between, on the one hand, the brackets 41 and 42 and, on the other hand, the beams 100 and 200, while ensuring that the grating 1 is fixed to the beams 100 and 200 in the fixing position F. Thus, the 1000 fitting more easily absorbs thermal expansion in the fixing position F. The brackets 41 and 42 can move slightly within the openings 104 and 204 along the horizontal longitudinal Y direction and the vertical Z direction. The stops 102 and 202 retain the brackets 41 and 42, and therefore the grating 1, on the beams 100 and 200 in the fixing position F.

[0073] Legs 41 and 42 eliminate the need for locking hooks that require rotation to move from an initial rotating position, freeing the grating from the beams, to a position where the hooks are secured under beams 100 and 200 to immobilize the grating. The drawback of these rotating hooks is their tendency to break.

[0074] In the fixing position F, an upper portion 413 of the front leg 41 rests on an upper surface 108 of the front beam 100. The upper portion 413 of the front leg 41 is connected to its first front end portion 411 by intermediate portions 414 angled relative to it. The upper surface 108 of the front beam 100 is located behind the first groove 101, which is below the level of this upper surface 108. The upper portion 413 of the front leg 41 is fixed below the lower surface 3 of the grating 1.

[0075] In the fixing position F, an upper portion 423 of the rear leg 42 rests on an upper surface 208 of the rear beam 200. The upper portion 423 of the rear leg 42 is connected to its second rear end portion 421 by an intermediate portion 422 angled relative to them. The upper surface 208 of the rear beam 200 is located forward of the second groove 201, which is below the level of this upper surface 208. The upper portion 423 of the rear leg 42 is fixed below the lower surface 3 of the grating 1.

[0076] The front beam 100 and / or the rear beam 200 can be made of metal (for example, aluminum) or another material. The front beam 100 and / or the rear beam 200 can be made from a profile along the X direction, this profile having a central cavity, which makes the beam lighter and easier to handle. Equipment installation procedure

[0077] A method for installing equipment 1000 in structure 2000 for swimming pools is described below with reference to figures 17A, 17B, 17C, 17D , 17E and 17F Previously, the first beam (100 mm front) and the second beam (200 mm rear) were fixed between the right and left walls. The first beam (100 mm front) is positioned forward and at a non-zero distance along the horizontal longitudinal direction Y relative to the second beam (200 mm rear).

[0078] The installation process involves the following steps.

[0079] During a first stage E1, illustrated in Figures 17A and 17B , we tilt the rear 13 of the grating 1 downwards and backwards to insert the rear tab 42 into the second groove 201. During this first step E1, the front tab 41 is above the first groove 101.

[0080] In a second step E2, which is subsequent to the first step E1 and which is illustrated in Figures 17A and 17B, we translate the grating 1 towards the rear to insert the second rear end part 421 of the rear leg 42 into the second opening 204 and to put the second rear end part 421 under the second stop 202.

[0081] During a third step E3, which is subsequent to the second step E2 and which is illustrated in Figures 14 , 17C and 17D , we tilt the front 14 of the grating 1 downwards to insert the front leg 41 into the first groove 101 and to insert the first front end part 411 onto the first stop 102 in an intermediate position I.

[0082] During a fourth step E4, which is subsequent to the second step E2 and which is illustrated in Figures 15 , 17E and 17F, we tilt the front 14 of the grating 1 downwards to insert the front leg 41 into the first groove 101 and to insert the first front end part 411 under the first stop 102 in the fixing position F.

[0083] The material of the legs 41 and 42 exhibits a certain aptitude for bending during the steps E1, E2 and E3 to reach the fixing position F.

[0084] According to an embodiment of equipment 1000, as illustrated in Figures 14 And 15 The first stop 102 has an upper guiding surface 1021, which is inclined forward from bottom to top. The first front end portion 411 of the front leg 41 has a lower front end 412, which has a front surface inclined backward from top to bottom. This embodiment can be used in the installation process, by virtue of the fact that, from the third step E3 of the Figures 14 And 17Dat the fourth stage E4 of the Figures 15 And 17F The lower front end 412 of the front leg 41 is lowered against the upper guide surface 1021 of the first stop 102. By bending this lower front end 412, the upper surface 1021 of the first stop 102 is then moved downwards by the front edge 14 of the grating 1, thus placing the first front end portion 411 in the first opening 104 under the first stop 102 in the fixed position F. The upper guide surface 1021 is substantially parallel to the front surface of the lower front end 412 and serves to guide this front surface of the lower front end 412 as it descends against the upper surface 1021 from the third step E3 to the fourth step E4.

[0085] According to one embodiment of equipment 1000, the second part 205 of the wall is less inclined downwards than the first part 105 of the wall.

[0086] According to an embodiment of equipment 1000, the second part 205 of the wall is horizontal. Rear beam variant

[0087] According to an embodiment of equipment 1000, illustrated in figures 18 And 19 , which is a variant of the equipment 1000 described above, it is provided in place of the rear beam 200 described above a rear plate 200' (or rear bar 200') fixed against the front surface 2003 of the rear vertical wall 2002.

[0088] The 200' rear plate has a 104' recess analogous to the 104 opening but oriented towards the front.

[0089] The fastening means 4 comprise the front tab 41 described above and, in place of the rear tab 42 described above, a rear tab 42', which has the same shape as the front tab 41 but is oriented in the opposite direction to the front tab 41. The rear tab 42' comprises the parts 411', 412', 413', 414' having the same shape as respectively the parts 411, 412, 413, 414 described above.

[0090] At the top of the rear plate 100' is the stop 102', which protrudes forward and adjoins the recess 104' with a downward-facing horizontal edge 109'. The rear plate 200' may be in the form of a locking profile.

[0091] The first rear end portion 411' of the rear leg 42' is positioned below the stop 102' in the fixing position F. The first rear end portion 411' of the rear leg 42' may be in contact with the stop 102' in the fixing position F or may be at a non-zero vertical distance below the stop 102' in the fixing position F. In the fixing position F, the grating 1 is located on the rear vertical wall 2002. The rear plate 100' may be fixed against the front surface 2003 of the rear vertical wall 2002 by one (or more) stud(s) 2004 screwed into a piece 2005 sealed in the rear vertical wall 2002 or by other means of fixing, such as by bonding.

[0092] The grating 1 can be removed by inserting a T-shaped rod (or a T-shaped screwdriver or an oblong T-shaped tool) from top to bottom through the hole 5 and towards the front tab 41, in a manner similar to that described below with reference to Figures 20A and 20B . Grating plug

[0093] Following an embodiment of the grating 1, as illustrated in figures 20A, 20B , 21, 22 , 23, 24A, 24B , 25A, 25B, 26A, 26B , the grating 1 has at least one vertically passing hole 5, which is located above the first front end part 411 of the front leg 41.

[0094] The vertically passing hole 5 can be located in another front end part 50 of the grating 1.

[0095] The other front end part 50 of the grating 1 can be formed by a front plug 51, which is fixed relative to the main profile 11.

[0096] One of the advantages of the 51 front cap is that it helps to limit the proliferation of algae in the interstices.

[0097] The grating 1 may include a front support 61, which is fixed to a front end 111 of the main profile 11.

[0098] The front cap 51 can be fixed against the front support 61, for example by clipping.

[0099] As illustrated in the figure 21 The front support 61 can be fixed to the front end 111, for example by screws 611 (e.g. self-tapping screws) which are screwed into receiving parts 612 (e.g. screw recesses) provided in the front end 111 of the main profile 11 and shown in the Figures 1 , 4 And 8. The receiving portions 612 may be provided only in the front end 111 of the main profile 11 and not along its entire length between the front end 111 and the rear end of the main profile 11. The front support 61 may include rear extensions 613 (or rear islands 613), which are connected at the front to a flange 618 and are housed in cavities 119 surrounded by frames 614 of the main profile 11. The screws 611 pass through the flange 618, which is positioned against the front end 111. The rear extensions 613 may terminate at the rear with a transverse face 619 (which may have a hole 620), located further back than the flange 618. These rear extensions 613 thus help to position the front support 61 against the main profile 11. In the main profile 11, the part upper 126, lower surface 3, walls 1141, 1151 and other intermediate reinforcing walls connecting them can form these frames 614.The receiving parts 612 can be located next to the cavities 119 and be connected to one or more of the frames 614. The front plug 51 can be in one piece of a synthetic material, for example made by injection of a plastic material (for example in ABS), or other.

[0100] One advantage of this is that the cap 51 can be easily replaced and can have a finish or appearance, which are chosen to be different or identical to the upper surface 2. The front support 61 can be in one piece of synthetic material, for example made by injection of a plastic material (for example in ABS), or other.

[0101] In the embodiment, illustrated in figures 21, 22 , 23, 24A , 24B , 25A, 25B, 26A, 26BFor clipping the front cap 51, the front support 61 may include a lower tab 616 projecting forward (for example, from a rear face of a rear extension 613) and one (or more) upper holes 617 facing forward. The lower tab 616 has a lower lug 621 projecting downward. The front cap 51 has a front wall 511 connected to an upper wall 512 having a vertically through hole 5 and to a lower wall 513 having a vertically through lower hole 514 and another vertically through lower hole 5145. The front wall 511, the upper wall 512 and the lower wall 513 can be connected on the right to a side wall 515 and on the left to a side wall 516. The front plug 51 has one (or more) upper guide finger 517 extending rearward.The upper guide finger(s) 517 terminates in an upper rear hook 518 oriented upwards.

[0102] To clip the front cap 51 against the front support 61, the upper finger(s) 517 is inserted into the upper front hole(s) 617 in a first oblique position of the cap 51 relative to the support 61, as shown in the diagrams. Figures 24A and 24B , the lower wall 514 being moved aside in front of the lug 621.

[0103] Then the cap 51 is moved rearward against the front support 61, to insert the rear upper hook 518 near the rear of the rim 618 and to insert the lower lug 621 of the lower tab 616 into the lower hole 5145 in a second oblique position of the cap 51 relative to the support 61, as shown in Figures 25A and 25B .

[0104] Then the cap 51 is moved rearward against the front support 61, to insert the rear upper hook 518 behind the rim 618 and to insert the lower lug 621 of the lower tab 616 into the lower hole 514 in the clipped position of the cap 51 relative to the support 61, as shown in Figures 10 , 11 , 12 , 14 , 15 , 16 , 17A, 17B, 17C, 17D , 17E, 17F , 18 , 19 , 20A, 20B , 22 , 26A and 26B .

[0105] In the embodiment, illustrated in Figures 21 , 24B , 25B and 26BThe lower tab 616 of the front support 61 itself has another vertically passing hole 6160. This other hole 6160 is located rearward relative to the lower lug 621. The lower lug 621 may be oblong, being longer in the X direction from left to right than in the Y direction from back to front. The lower hole 514 may have an oblong locking portion 5140, which is longer in the X direction from left to right than in the Y direction from back to front, as illustrated in the figure 23In the clipped position, the lower lug 621 is located within the oblong locking portion 5140 of the lower hole 514. The oblong locking portion 5140 thus serves to lock the plug 51 in its clipped position. The lower hole 5145 can be connected to the oblong locking portion 5140 of the lower hole 514, which is situated in front of the lower hole 5145. In the clipped position, the hole 6160 is vertically opposite the hole 5 and vertically opposite the lower hole 5145. The hole 6160 and / or the hole 5 and / or the lower hole 5145 can be circular.

[0106] In an alternative, not shown, to the above embodiment, the tongue 616 does not have a hole 6160. The lower hole 5145 is provided in front of the lower hole 514, and may have the oblong part 5140 for locking the lower hole 514. The lower hole 5145 is not connected to the lower hole 514.

[0107] The grating 1 may include a rear support 62, which is fixed to a rear end 112 of the main profile 11, and a rear end cap 52, which is fixed against the rear support 62, for example by clipping, as shown in the figure 12 .

[0108] The rear cap 52 can be analogous to the front cap 51, without the hole 5 and without the lower hole 5145, by reversing the term front and the term rear.

[0109] The rear support 62 can be analogous to the front support 61, without the hole 6160, by reversing the front and rear terms.

[0110] The plug 51 described above prevents gluing on each rail 10. The plug 51 described above also prevents finishing on the profiles 11 and 12. The plug 51 described above can also be replaced.

[0111] In the clipped position of the front cap 51 and in the fixing position F of the grating 1 on the beams 100 and 200, a user can insert a rod T (or a screwdriver T or an oblong tool T) from top to bottom through hole 5, through the lower hole 6160 and through the lower hole 5145, then into the first groove 101 of the beam 100 towards the front tab 41, as shown in the figure 20A By the user moving the rod T downwards through hole 5 and the lower hole 5145 against the front tab 41, the rod T levers the front tab 41, lowers and moves the first front end portion 411 rearward relative to the first stop 102, and then passes between the first front end portion 411 and the first stop 102, as shown in the figure 20BThe first front end part 411 is then no longer in the first opening 104 under the first stop 102 in the release position L shown in the figure 20B The user can then dismantle the grating 1 in relation to beams 100 and 200.

[0112] To dismantle the grating 1 in relation to beams 100 and 200 from the release position L shown in the figure 20B , the user performs the reverse steps of those E1, E2, E3 and E4 of the installation process, namely: tilting the front side 14 of the grating 1 upwards and over the front beam 100 to exit the first groove 101 the front leg 41, then translating the grating 1 forwards to exit the second opening 204 the second rear end part 421, then tilting the rear side 13 of the grating 1 upwards and over the rear beam 200 to exit the second groove 201 the rear leg 42.

[0113] This allows the grating to be dismantled with less risk of breakage compared to the beams. Receiving cavity

[0114] Following an embodiment of the grating 1, as illustrated in Figures 1 , 4 , 8 , 11 , 12 And 21The main profile 11 has in its lower surface 3 one (or more) mounting surfaces 1130 extending along the Y direction from front to rear. Above each mounting surface 1130 is a receiving cavity 113 extending along the Y direction from front to rear. The mounting surface 1130 can be traversed from top to bottom by one (or more) first mounting members 116 for the front bracket 41, the mounting member 116 then entering the receiving cavity 113. The mounting surface 1130 can be traversed from top to bottom by one (or more) second mounting members 117 for the rear bracket 42 and / or 42', the mounting member 117 then entering the receiving cavity 113.

[0115] The first fastening member 116 may include a first screw (for example, a thermoplastic screw) which passes through a hole 43 in the front tab 41, is screwed into the fastening surface 1130, and enters the receiving cavity 113. The second fastening member 117 may include a second screw (for example, a thermoplastic screw) which passes through a hole 44 in the rear tab 42, and / or 42', is screwed into the fastening surface 1130, and enters the receiving cavity 113.

[0116] This allows the user to choose along the Y direction the place in the 1130 fixing surface where he wants to fix the first 116 fixing element of the front leg 41 and the second 117 fixing element of the rear leg 42 and / or 42', to adjust their position in the desired way.

[0117] The mounting surface 1130 may have a notch 1131 extending from front to rear in the lower surface 3. This notch 1131 (or marking notch 1131) serves both to better locate the mounting surface 1130 from the outside and to facilitate the insertion into it of the first mounting member 116 for the front leg 41 and the second mounting member 117 for the rear leg 42 and / or 42'. The notch 1131 may be V-shaped.

[0118] At least two fixing surfaces 1130, at least two receiving cavities 113 and at least two notches 1131 may be provided, each of which is situated between two parts 31 and 32 located under the cavities 119 and for example between two of the frames 614.

[0119] As represented at Figures 11 , 12 and 13The mounting surface(s) 1130 and the notch(s) 1131 can also be used to adjust the front-to-back position, along the Y direction, of several third mounting elements 71 for the cross member 7 to the rails 10, when several rails 10 are provided. Each third mounting element 71 may have a third screw, which passes through a hole 72 in the cross member 7, is screwed into the mounting surface 1130, and enters the receiving cavity 113. One of the holes 72, several of the holes 72 or all of the holes 72 of the cross member 7 may be oblong along the horizontal transverse direction X to also allow adjustment of the positioning of the rails 10 relative to each other from left to right, for example to have a gap between 0 and 4 mm between the rails 10. This also allows variation of the total width of the grating 1 between left and right. Mounting rail

[0120] Following an embodiment of the grating 1, as illustrated in Figures 11 , 12 , 14 , 15 , 16 , 17A, 17B, 17C , 17D , 17E , 17F , 20A , 20B And 27 , the front leg 41 is part of a first fixing rail 410 and the rear leg 42 is part of a second fixing rail 420.

[0121] The first 410 fixing rail can have an identical shape to that of the second 420 fixing rail (or 410' to the figure 18Thus, in this case, the first fixing rail 410 has the front tab 41 described above, connected at the rear to the upper part 413, itself connected at the rear to a rear part 415 of identical shape to that of the rear tab 42. Thus, in this case, the second fixing rail 420 has the rear tab 42 described above, connected at the front to the upper part 423, itself connected at the front to a front part 425 of identical shape to that of the front tab 41. Consequently, under the lower surface 3 of the grating 1, one (or more) first fixing rail 410 is fixed, which is further forward in the Y direction than one (or more) second fixing rail 420 fixed under the lower surface 3 of the grating 1. The rear part 415 is left free behind the front beam 100 in the fixing position F. The front part 425 is left free in front of the rear beam 200 in the fixing position F.

[0122] This allows only one rail shape to be manufactured to form the first 410 fixing rail and the second 420 fixing rail, as shown in the figure 27 .

[0123] The first 410 fixing rail and the second 420 fixing rail can each be made from a profile along the X direction. The first 410 fixing rail and the second 420 fixing rail can be metallic (e.g., aluminum) or made of another material. The first 410 fixing rail and the second 420 fixing rail can be made of stamped sheet metal (e.g., aluminum).

[0124] The first fixing rail 410 and the second fixing rail 420 may have as holes 43, 44, one (or more) oblong holes 430 along the Y direction, to allow adjustment in position of the fixing member 116 and / or 117 along the Y direction.

[0125] The first fixing rail 410 and the second fixing rail 420 may include a portion 416 bent downwards in a U-shape, as shown in Figures 11 , 12 , 17A, 17B, 17C, 17D , 17E, 17F , 18 20A, 20B , 27 This downward-projecting part 416 can be inserted into an upper recess of the beam 100 or 200. This part 416, bent downwards into a U shape, can be used to counteract the expansion of the grating 1. Beam height adjustment parts

[0126] Following a method of implementation of the 2000 structure, illustrated in figures 28A, 28B , 29A, 29BThe structure 2000 includes means 300 for adjusting the height (vertically along the Z direction) of the first front beam 100 and / or the second rear beam 200 relative to the right and left walls. These means 300 can allow the height position of the first front beam 100 and / or the second rear beam 200 to be varied, for example, by a value of up to 20 mm.

[0127] According to an embodiment of the structure 2000, for each beam 100 and 200, the adjustment means 300 comprise a receiving shoe 301 for the right end of the beam and another receiving shoe 301 for the right end of the beam.

[0128] Each bracket 301 has a lower support face 302 under the end of the beam. The lower face 302 is connected upwards to a front face 303 and a rear face 304, which are aligned along the horizontal longitudinal direction Y for receiving the end of the beam. The lower face 302 is connected upwards to an adjustment side face 305, which is connected to the front face 303 and the rear face 304. The lower face 302, the front face 303, the rear face 304, and the adjustment side face 305 define an internal recess 310 into which the end of the beam is received.

[0129] The adjustment means 300 further include an anchoring piece 306, which must be fixed to the right or left wall. The adjustment side face 305 has one (or more) oblong hole 307 in the vertical direction Z for adjusting the bottom-to-top position of the bracket 301 relative to the anchoring piece 306. One (or more) screw 308 is screwed into the oblong hole 307 to immobilize the bracket 1 against the anchoring piece 306 in the height-adjusted position. figures 28A And 29A The 301 shoe can therefore be positioned lower than at figures 28B And 29B compared to anchor part 306.

[0130] The adjustment means 300 thus allow the use of gratings 1 of different thicknesses (in height along the Z direction) without having to modify the position of the anchoring part 306 to have the same positioning in height of the upper surface 2 of the gratings 1. The adjustment means 300 also allow to correct inaccuracies or errors in the installation of the anchoring part 306 in height.

[0131] Anchor piece 306 can be a piece to be sealed into the right or left wall. Figures 28A and 28B . In this case, the screw(s) 308 can be inserted from inside the shoe 1 through the oblong hole(s) 307 to pass through the part to be sealed.

[0132] Anchor part 306 can be a plate screwed into the right or left wall. Figures 29A and 29BIn this case, the screw(s) 308 are fixed to the plate and protrude from it. The shoe 1 is positioned to place the oblong hole(s) 307 around the screw(s) 308 and to screw one (or more) nut(s) 309 around the screw(s) 208 protruding from the lateral adjustment face 305 and located in the shoe 31. The anchoring piece 306 can be metallic (for example, stainless steel) or other.

[0133] According to one embodiment of structure 2000, the end of the beam is fixed to an end fitting having a shape complementary to that of the housing 310 of the bracket 301, so that this end fitting can be fixed in the housing 310 of the latter. In this case, the end of the beam is replaced above by the end fitting. The end fitting can be press-fitted against the end of the beam or screwed onto the end of the beam.
