Description


  
 



   "System and method for renovating a staircase, and tools
 dimensional statement for implementation
 of this process "
 DESCRIPTION
 The present invention relates to a system for renovating a staircase. It also relates to a process implemented in this system, as well as dimensional survey tools used for this implementation.



   There is currently a significant demand for staircase renovation, originating both in aesthetic motivations or in reducing noise pollution and in needs to improve safety, in particular when old degraded stairs are used by elderly people or people with reduced mobility.



   Several stairway renovation systems are already known which aim to dress old wooden staircases or concrete staircases, and more particularly methods using aluminum corner profiles placed at the level of each stair nosing.



   Thus, the document EP0515720 discloses a staircase renovation system using a corner profile designed to receive on its horizontal part a step panel and on its vertical part a step nose. The angle profile has on its vertical part a lug designed to be inserted into an oblique slot made in the internal face of the stair nosing, and is screwed onto the old stair step. An anti-slip seal is embedded in an interstice existing between the step panel and the upper part of the step nose.



   Also known from patent FR 9312989 is a staircase renovation system using an aluminum profile which is screwed to the end of the existing stair nosing and which is arranged to receive a plate of optionally molded material acting new stair nosing. This aluminum profile has on its upper part a flap extending towards the outside of the step so as to maintain the new stair nosing and having a rounded shape so as to ensure continuity between the surface of the step and the surface of the new stair nose.



   In another staircase renovation system, an aluminum profile directly constitutes a new stair nosing and is designed to be fixed by screws to the step and to receive on the one hand, in an upper housing, a cover panel for step resting on a layer of foam, and on the other hand in a lower housing, a riser cover panel.



   Document DE4133721 discloses a staircase renovation system implementing a profiled support piece which is fixed beforehand by screwing both on the initial step plan and on the initial riser so as to enclose an initial step nose. In this renovation system, a new step panel and a new riser are then arranged so that they partially cover respectively horizontal and vertical parts of the profiled support piece, then a nose piece is then fitted onto a projecting part. U shape of the profiled support piece until it mates with a tongue arranged on the lateral edge of the new step panel and in abutment against the new riser. The nose piece is attached to the projecting part of the support piece by gluing.



   The object of the invention is to propose a staircase renovation system which leads to better aesthetic rendering and greater solidity than existing systems, while being easy and quick to implement.



   The aforementioned objectives are achieved with a system for renovating a staircase comprising a set of steps each initially comprising a step plan, a riser and a possible step nose, this system comprising in at least one of said steps a new step nose including:

   profiled support means intended to be fixed to the step and comprising a nose support part projecting substantially in the extension of the step plan and comprising an upper face and a lower face connected by a lateral face, and -a part nose also of the profiled type comprising (i) a recess arranged to receive in insertion the nose support part, and (ii) an upper part and a lower part having their respective ends arranged to receive respectively a step panel and a panel risers placed respectively on the initial step plan and riser.



   According to the invention, the new stair nose also comprises means for fixing the lateral face against a corresponding internal face of the nose piece, these fixing means being designed to be implemented before the fixing of the profiled support means. , and the end of the upper part of the nose piece is located above the initial plan.



   With this new stair nosing configuration, a particularly robust and aesthetic end result is obtained. Indeed, it is no longer necessary to provide a joint between the new step plan and the new stair nosing. Furthermore, the prior fixing of the new stair nose to nose support means which are then fixed to the step contributes both to a remarkable gain in terms of robustness and to a significant reduction in the duration of the renovation operations. , in comparison with existing systems.



   In addition, the fact that the upper part of the nose piece extends above the initial running plan, combined with a close fixing of the lateral face of the nose support part and the corresponding inner face of the piece nose, contributes to significantly increase the mechanical strength of the new stair nosing compared to previous achievements.



   It thus becomes possible to have a staircase renovated in a new decoration, in a reduced period of time, without causing damage or dust. In addition, the new stair nosing thus obtained advantageously replaces the old used stair nosing without reducing or increasing the anterior surfaces.



   The assembly constituted by the wooden profile and the aluminum profile contributes to re-establish a new horizontal plane compared to the old horizontal plane degraded by wear, which allows if necessary to reschedule with means of rearrangement.



   In addition, the elimination of the old stair nosing allows a stylobate to be cut with right angles, and consequently contributes to significantly reducing the duration of the laying operations and therefore the renovation costs.



   The nose support means can for example be made from an aluminum profile, while the nose piece fixed to the nose support means can be made from a solid wood profile.



   In a practical embodiment, the fixing means comprise fixing screws placed in holes or perforations provided on the side face.



   When the profile support means further comprise an upper wing substantially in the extension of the support part and intended to be fixed to the initial working plane, this upper wing may advantageously be provided with perforations allowing optimal use of a fixing glue between this upper wing and the initial route plan.



   Likewise, when the profile support means further comprise a lower wing intended to be fixed to the initial riser, this lower wing may also be provided with perforations, as well as the faces of the nose support part.



   In another embodiment, the lateral face of the nose support part is inclined at an angle determined relative to the vertical and in that the nose piece has a recess having an inner wall of substantially the same inclination as said lateral face. This allows for a strut effect contributing to an increase in the pressure resistance of the new stair nosing.



   When the profile support means further comprise an upper wing substantially in the extension of the support part and designed to be fixed on the initial working plan, it can advantageously be provided that this upper wing comprises an inclined part breaking between the upper face of the nose support part and a part for fixing to the initial running plan. This makes it possible in particular to provide a sufficient gap for a layer of glue, and / or to have a new working plan of significant thickness in the case of a significant break.



   In a first alternative embodiment of a renovation system according to the invention, the lower part of the nose piece is spaced from the lower wing of the profiled support piece by a distance sufficient to receive the upper end d 'a new riser.



   In a second alternative embodiment, the lower part of the nose piece is shaped to come into substantial abutment against the lower wing of the profiled support piece and to receive the upper end of a new riser.



   When the renovation system according to the invention is applied to a concrete or stone staircase, the profiled support means can comprise a nose support part in which the upper face and the lower face are substantially in contact.



   According to another aspect of the invention, there is provided a method for renovating a staircase comprising a set of steps each initially comprising a step plan, a riser and possibly a step nose, implemented in the renovation system according to the invention. invention, this method comprising for at least one of said steps an installation, possibly in substitution of the initial stair nosing, a new stair nosing and a covering of the initial walking plan and of the initial riser respectively by a walking panel and a riser panel.



   This method is characterized in that it further comprises the following steps: -fixing a profiled nose piece beforehand to a profiled nose support piece, -fixing the profiled nose support piece thus equipped in terms of initial step and the initial riser, possibly after removal of the stair nosing, then -installation of the riser panel and the step panel with engagement of lateral edges of said panels in respectively upper and lower receiving housings formed between the support support part profiled nose and the profiled nose piece.



   The profiled nose support piece is preferably previously screwed and glued to the bottom of a housing formed in the profiled nose piece.



   Advantageously, there may be provided a preliminary step for raising the dimensions of the step plans, risers and any stylobates of the staircase, as well as a step for installing at least one stylobate for the staircase to be renovated, prior to the steps of fixing of the new stair nosing and installation of the panels.



   According to yet another aspect of the invention, there is provided a tool for raising the dimensions of a plinth or a stylobate for a staircase, used in the renovation process according to the invention, characterized in that it comprises a set of articulated elements adjustable in length and arranged to substantially match the external contour of at least one stair step.



   There is also proposed a tool for reading the dimensions of a step plan on a staircase, used in the renovation process according to the invention, characterized in that it comprises a main part designed to be placed on the step plan at the edge of the stair nosing and probe assemblies fixed to said main part and adjustable by sliding and clamping, each probe assembly being arranged to be disposed in abutment against a side wall of the staircase or against a riser.

   We will now describe, with reference to the above figures, embodiments of a renovation system at the same time as the essential steps of the process implemented in this system, applied to the renovation of a wooden staircase. The renovation system according to the invention aims to achieve, on the one hand, a covering, with wooden or other material panels, of floor plans and risers of an existing staircase, of wood or concrete, and d on the other hand to install new stair noses, possibly replacing existing stair noses in the case of used wooden stairs.



   In a first version applied to wooden staircases, the system includes, with reference to FIG. 1, an implementation, for each step of a staircase E, of the following elements:
 a new stair nose consisting of a profiled nose piece 2, for example of solid wood, screwed and glued to a profiled nose support piece 3, for example of aluminum, this support piece 3 being fixed with a part to the initial PM plan and secondly to the initial riser CM;
 a step panel 4 arranged to cover the initial step plan PM and configured to be fitted with the upper part of the profiled nose piece 2;

   and
 a riser panel 5 arranged to cover the initial riser CM and configured to be inserted between the lower part of the profiled nose piece 2 and the profiled support piece 3.



   The profiled support part 3 comprises a support part 30 comprising a horizontal upper face 31 extending to produce an upper wing 34 intended to be placed in abutment against the initial working plane PM, a vertical lower face 33 extended by a wing vertical lower 35 intended to be placed in abutment against the initial riser CM, these two upper and lower faces 31, 33 being connected by a lateral face 32 extending beyond the angle of the step.



   The profiled support piece can be made of a material of small thickness, for example 1/10 mm, without this indication of thickness being able to be considered as limiting.



   The profiled nose piece 2 includes a recessed area open on the inside of the piece and configured to receive the support portion 30 in an adjusted manner, and an exterior area having a substantially rounded shape on its upper portion 23 to produce the more advanced of the new stair nose. The upper part 22 of the nose piece 2 is substantially flat and configured to be in the extension of the upper surface 42 of the step panel 4 provided with a tongue 47 intended to be fitted into a rebate 27 formed in the upper part 22 of the nose piece 2, while the lower part of the nose piece 2 has a heel 26 arranged so as to leave sufficient space between the vertical lower wing 35 of the profiled support piece 3 and the end of this heel to receive the riser panel 5.



   The wooden profile 2 cannot be smaller or larger than the initial stair nosing, and must be thick enough to receive the aluminum profile which is glued and screwed into the lower part of said wooden profile.



  It has in its lower part a heel allowing an adjustment to adapt to the possible differences in thickness of the risers. It can be made of solid wood, but also of aluminum, PVC or in all types of wood and possible shapes.



   The horizontal upper wing 34 and the vertical lower wing 35 of the profiled support part 3 are provided with holes for the passage of fixing screws 36 respectively in the initial working plane PM and the initial riser CM, while the face lateral 32 of the support part 30 is also provided with a hole for the passage of a fixing screw 37 in the body of the nose piece 2.



   The end 27 of the upper part 22 of the nose piece 2, which constitutes a rebate adapted to receive the end tab of the new step panel 4, is located above the initial step plan
PM and therefore beyond the external vertical plane of the riser CM. This characteristic arrangement contributes to achieving a particularly solid new stair nosing.



   In another exemplary embodiment illustrated in FIG. 2, the lateral face 32 ′ of the profiled support piece 3 is inclined so as to produce an acute upper angle, which contributes by a strut effect to increase the resistance mechanics of the new stair nosing. The inclined lateral face 32 ′ is normally fixed to the corresponding internal face of the nose piece 2 ′ by means of fixing screws 37 ′. In addition, the upper wing 34 ′ of the profiled support piece 3 ′ has a break B adapted to allow the installation of step panels of appropriate thickness so that their upper face is flush with the upper face of the nose piece. , while allowing the use of a layer of adhesive C.



   As illustrated in FIG. 3, the implementation of the renovation system according to the invention makes it possible to obtain a new stair nosing 2 having a size substantially equivalent to that of the old stair nosing
AN, unlike renovation systems of the prior art and very particularly systems providing for coating of the old stair nosing with a new stair nosing.



   Optimizing the size of the new stair nosing provided by the renovation system according to the invention has the positive consequence of not involving excess thickness of the step and riser panels, thus avoiding the problems encountered at the upper or lower ends d stairs renovated according to renovation methods of the prior art.



   In a second version of the system according to the invention applied to the renovation of concrete staircases, this system 1B comprises, with reference to FIG. 4, a set of stair nosings constituted by the coupling of a wooden profile 2B and d '' a 3B aluminum profile, this set of stair noses being arranged to match the walking angle of an MB step in raw concrete. The aluminum profile 3B comprises a horizontal wing 34B intended to come into abutment against the existing step plan, a vertical wing 35B intended to come into abutment against the existing riser and a nose support 30B extending substantially in the plane of the horizontal wing 34B. The horizontal wing 34B, the vertical wing 35B and the nose support 30B are provided with a set of holes for receiving screws or fasteners suitable for the materials encountered.

   The step panels used for the renovation of concrete stairs have a significantly greater thickness than that of the panels used for the renovation of wooden stairs. The step panel 4B is provided with a tongue 47B arranged to be fitted into a rebate 27B provided on the rear upper part of the wooden profile 2B.



   We will now describe, with reference to FIGS. 5, 6A and 6B, several exemplary embodiments of profiled support parts which can be used in renovation systems according to the invention.



   In a first embodiment illustrated in FIG. 5, the profiled support part 3 comprises a nose support part 30 comprising a vertical lateral face 32 and respectively upper and lower fixing wings 34, 35, and is provided on all its perforation surface allowing optimal bonding conditions. By way of nonlimiting example, one can foresee a perforation rate of about 30%.



   In a second example of embodiment illustrated by FIGS. 6A and 6B, the upper part of the nose support part 30A, 30B of the profiled support part 6A, 6B has a break BA, BB so that the upper wing of fixing 34A, 34B is in a lower plane relative to the plane of the upper face 31 of the nose support part 30A, 30B. This offset can, for example, be of small value, as in the case of the variant embodiment shown in FIG. 6A, to allow the installation of a new step panel with a nominal thickness of 8 mm. However, this offset can also be greater, as in the case of the variant embodiment shown in FIG. 6B, to allow for example the installation of a new step panel 20 mm thick.



   We will now describe the main steps of an exemplary operating mode for implementing the renovation process according to the invention on a used wooden staircase E, in particular with reference to FIGS. 1,7 and 8.



   I) First, carefully cut the stair noses vertically from each CM riser.



   II) Next, set up SB stylobates, if provided (FIG. 7).



   III) We present the assembly consisting of the wooden profile 2 and the aluminum profile 3 previously cut to length, fixed between by screwing and / or gluing.



   IV) The set of profiles is fixed on the initial PM step support and on the initial CM riser.



   V) The set of fixed profiles is glued using a special silicone cartridge, taking care to overload with glue in certain places to compensate for flatness defects and thus restore the horizontality which is indicated by the profile aluminum stair nosing.



  It should be noted that in certain cases of too pronounced wear of the steps, a rearrangement may be necessary.



   VI) The step panel 4 is presented after having debited it with the measurements taken with the dimensional reading tool reserved for this purpose and described below.



   VII) Glue the rebate 27 of the wooden profile 2 and the tongue 47 of the step panel 4. Make sure that the bottom 48 of the step panel 4 does not abut against the old riser CM of the upper step in order to leave enough play (Figure 8).



   VIII) The step panel is hammered using a wooden block, then the upper riser panel 5 is presented, the lower end of which will mask the clearance between the bottom of the step panel 4 and the initial riser.



   This series of steps is reproduced for each step of the staircase to be renovated.



   It should be noted that the wooden panels used in the renovation system according to the invention can for example be coated 20 to 30 tenths of a millimeter in fine species (precious wood, oak, mahogany). They can be pre-debited on both sides in lengths designed to facilitate their handling in tight spaces such as are generally stairs.



  These wooden panels can also be pre-molded.



   We will now describe, with reference to FIG. 9, a first embodiment of an OS tool for detecting the characteristic dimensions necessary for the manufacture of a stylobate suitable for the staircase to be renovated.



   This tool was developed to measure the heights and depths of the steps, in order to determine the dimensions of the plinth or stylobate. For example, heights between 176 mm and 240 mm and depths between 200 mm and 500 mm can be recorded.



   More generally, the function of this first tool is to report on materials to be cut, either perpendicular lines in a vertical situation, of different lengths and heights, or diagonal lines also of different lengths and heights. One can also provide that this tool can take into account in its path a projecting obstacle, this function being performed by a thin sheet, for example stainless steel, folded and adapted on the tool by means of a light.



   Such a dimensional survey tool is for example made up of several square-shaped elements 9, 10 assembled by sliding parts 95, 105 allowing a double latitude of horizontal and vertical adjustment and which can be locked by means of adjustment knobs 96, 106. Each angle element 9,10 further comprises on its vertical part 92,102, a slot 99,109 intended to receive elements for fixing feeler elements 93, 94; 103.104 provided to come into abutment against NM stair noses and risers CM, these feeler elements being adjustable both in length and in angle by means of adjustment knobs 97.98; 107,108.



   In a second embodiment shown in Figure 10, the dimensional survey tool OS is made up of a set of arms 81,83,85 adjustable in length and connected by joints 82,84 equipped with knurled screws 821,841 for adjustment angular. Each arm 81,83,85 comprises a first section of aluminum profile 812,832,852 provided with an adjustment screw 813, 833,853 and a second section of aluminum profile 810, 830,850, connected by a slide 811,831,851 made of plastic material, for example in polyamide, adjustable in length by sliding and locking by means of adjustment screws 813,833,853.



   The joints 82, 84 are for example made by means of two aluminum parts which pivot on themselves and which can be locked at any angle without any tolerance. This blocking is achieved by means of a knurled screw and reliefs are for example formed on the two internal faces of the parts to replace the pivoting.



   For the measurement of the dimensions of the different step plans of a staircase to be renovated, it is possible to use a dimensional measurement tool such as that shown in FIG. 11 in an example of implementation on a balanced step of a staircase in progress. renovation.



   This dimensional reading tool OP comprises a main part 70 designed to be placed on a working plane PM at the edge of the stair nosing NM and produced from aluminum profiles on which are fixed probe assemblies 710,720,730,740 adjustable by sliding and tightening. Each probe assembly comprises a first rod adjustable in length 711,721,731,741 connected to the main part 70 by an adjustment block 713,723,733,743 in the form of a slider and provided with adjustment screws, each first rod carrying an adjustable connecting block to a second rod adjustable in length and in direction 712,722,732,742 at the end of which is arranged a feeler member 71,72,73,74 arranged to be disposed in abutment either against a side wall of the staircase, or against the riser CM,

   or against a pillar 75 of the staircase in the case of the feeler member 74 fitted with a specific connecting piece 745 and having a shape adapted to bear against an angular piece.



   An operator wishing to obtain a complete dimensional reading of a walking plan, for example for a balanced walking with reference to FIG. 5, places this OP reading tool on this walking plan with the following alignment, and the fourth feeler member 74 in support against an angle of the pillar 75.



   This second dimensional reading tool can thus comprise a main part consisting of an aluminum profile, for example of dimension 20mm x 20mm, on which polyamide sliders equipped with aluminum rods can circulate. Its central part is then fitted with a flat chamfered ruler, perpendicular and articulated so as to bring together all of the diagonal or straight lines parallel to the body of the tool.



  At the end of this second reading tool, two sets of similar rods are provided, equipped with flat rules, the size of which can be determined as a function of the smallness of the location where this tool is used. It should be noted that these sets of rods can be replaced by elements fitted with hoses articulated so as to raise curved lines. In addition, an adaptation of the tool can be provided so as to be able to take up forms received by means of a specially dimensioned profile adapted to the tool.



   These dimensional reading tools are intended to transfer all of the geometrical configuration of the step and the plinth at once, which saves significant time.



   Of course, the invention is not limited to the examples which have just been described and numerous modifications can be made to these examples without departing from the scope of the invention. Thus, the materials used for producing the nose support profile and the stair nosing profile can be other than aluminum and wood.
