Definitions
- the present invention relates to a staircase with variable configuration. To take account of each particular configuration, which determines the inclination of the stringers and the distance between steps, or can manufacture custom-made staircases, which are delivered assembled, or which are on the contrary assembled on site. Such staircases are expensive to manufacture as well as to install.
- staircases have an adjustable configuration but their constituent parts remain expensive. According to DE-A-1 778 509, a staircase is thus known, the steps of which have on each side two angles pierced with a hole to allow the clamping of the stringers in an adjustable position. These steps are expensive to manufacture with several welded parts. Different steps must be in stock for the different stair widths. The rigidity of the staircase depends on the rigidity of the angles.
- the object of the invention is to propose a staircase with variable configuration which is particularly simple to make and install.
- the staircase with variable configuration comprises two parallel stringers, steps intended to extend parallel to each other between the two stringers, and means for fixing the steps in adjustable position between the two stringers, characterized in that the fixing means comprise for each step at least one rod extending over the entire width of the step and at each end of which is mounted a respective clamping means for urging the two stringers towards each other with compression of the step forming a spacer.
- the steps are fixed like simple spacers between the stringers, they can if desired be obtained by simply cutting a profile. There is no longer any need to add lateral fixing wings to them.
- the assembly is very fast, and the rigidity of the assembly obtained is improved thanks to the rigid and compressed bracing that the steps define between the stringers.
- the presence of at least one rod over the entire width of the step strengthens it against bending without the weight of the user or users.
- To make a staircase with a determined width it suffices to cut the profile of the steps to the corresponding length, and to use rods of correspondingly length.
- the assembly of the staircase can be a simple and fast operation, requiring neither particular qualification, nor complex tools.
- the clamping means can be removable, allowing the staircase to be dismantled and reassembled on another site, with another configuration.
- This variable configuration staircase, the steps and the two strings of which are preferably made of aluminum profiles, may have other characteristics.
- the stringers can be reinforced with sliding steel parts inside the aluminum profile.
- screwable brackets and sectors can be provided with the staircase.
- the staircase can be sold as a kit.
- FIG. 1 is a perspective view of a step of the staircase and two stringers with a tearing showing the means fixing the step to 1imon;
- FIG. 2 is a top view of the staircase showing a step, the profiles of the two lateral stringers and four corresponding fixing means;
- FIG. 3 is a detailed view of one of the fixing means
- FIG. 4 is a side view showing the inclined lateral stringer and by transparency two successive horizontal steps and their associated fastening means, another possible inclination of the stringer being shown in dotted lines;
- FIG. 5 is a side view showing a complete lateral stringer and the means for fixing this stringer to the ground and flat against the vertical wall against which the staircase is supported;
- FIG. 6 is a perspective view of the part that can be cut into two sectors adaptable to the ends of the stringer
- FIG. 7 is a side view showing a complete lateral stringer in position on site and the two sectors adaptable to the ends of the stringer;
- FIG. 8 is a sectional view of an alternative embodiment of a step.
- the staircase comprises two lateral parts - or stringers - (1) made of aluminum profile and steps (2) extending parallel to each other each between the two stringers.
- each profile or stringer facing the other stringer, is extended along each of its edges by two clamping wings (4) each terminated by a guide rib (6) bent in the opposite direction to the other silt.
- the two lateral edges of the step are placed against the wall (3) of the two opposite stringers.
- In the vicinity of the four angles of each step are mounted four pivoting shoes (7, 8) each having a groove (9).
- Each shoe is, at least before tightening, freely orientable relative to the plane of the step around an axis (39) parallel to the width of the step.
- each shoe is immobilized to avoid rotations around its axis (39) relative to the corresponding stringer.
- the grooves (9) of the shoes overlap the ribs
- Each shoe has two clamping faces. These two clamping faces are located on either side of the groove (9) on each shoe. They have an offset corresponding to the thickness of the wing (4).
- One (38) (fig.3) is designed to rest against the corresponding side edge of the step, and the other
- (II) is designed to bear against a tightening face (41) of the stringer opposite to the step, and carried by the tightening wing (4).
- the two front shoes (7), located at the two ends of the stair nosing (12), are crossed by a common anterior threaded rod (13) extending inside the step along the stair nosing, in a diameter housing very slightly larger than that of this rod. So the anterior threaded rod
- the two rear shoes (8), adjacent to the rear edge (14) of the step, are identical to the front shoes (7). They are crossed by a common posterior threaded rod (16) passing inside the step.
- this rear threaded rod (16) can slide freely in a housing (19) located inside the step and under the upper plane P of the step (2).
- This housing (19) extends along the rear edge (14) of the step with a certain depth in the direction of the step nose, and a height very slightly greater than the diameter of the threaded rod (16).
- the rear threaded rod (16) of each step is located at a freely adjustable distance from the front threaded rod (13).
- Each shoe is associated with a nut (17) screwed onto the threaded rod.
- Each shoe can, by screwing the nut (17) on the corresponding threaded rod, be biased towards the step which carries it.
- the hooves thus clamp the stringers against the steps, which form spacers between the stringers.
- the threaded rods reinforce the steps against bending.
- the step (2) will thus be fixed on the two stringers in a position freely chosen by the user.
- the height of the staircase is adjusted.
- the step (2) can be pivoted around the front rod (13) to more or less offset the rear hooves (8) relative to the front hooves (7) of the step relative to the length of stringers.
- This correlatively varies the distance between the front (13) and rear (16) rods of the step, by sliding the rear rod (16) in the housing (19). This adjusts the inclination that is planned to give the stringers when the staircase is installed, it being understood that it is generally desired that the plane P of the steps is horizontal.
- each front (7) and rear (8) shoe includes a retaining face (36; 46) which in service is parallel and adjacent to a longitudinal support face (37; 47) formed on the stringer so as to be oriented upwards when the stringer is in the inclined position on the installed staircase.
- a retaining face (36; 46) which in service is parallel and adjacent to a longitudinal support face (37; 47) formed on the stringer so as to be oriented upwards when the stringer is in the inclined position on the installed staircase.
- step (21) which is such that the two extreme positions of the rear rod (16) are on a line L (Fig. 2) inclined rearward relative to the plane of the step .
- this allows to lower the rear rod relative to the plane P of the step, in other words to raise the rear of the step relative to the plane defined by the two rods (13, 16).
- Each stringer has a hollow profile body (22) of generally rectangular section into which a reinforcing profile (42) can be slid (right part of FIG. 2), for example made of steel, in particular with a view to reducing the flexibility of the stairs. very long.
- the hollow profile body has, along its front and rear internal faces, parallel to the bending axis X of the stringer, two longitudinal ribs (23) allowing the reinforcement profile to slide without play, but without excessive friction, at the inside the hollow body (22).
- the stringers tend to bend, they are prevented by the support of the ribs (23) against the reinforcing profile (42).
- each stringer also has two reinforcing appendages (24) and (26).
- the first (24) is connected to the front face of the hollow body (22) facing the stair nosing.
- the second (26) is connected to the rear face of the hollow body (22) facing the rear edge of the step.
- the front appendage (24) has on its face turned away from the other stringer, a T-shaped groove (27) for fixing accessories such as a railing.
- brackets (28) are provided which can be fixed in an adjustable angular position against the external face of the stringers, so that the free wing (29) of these brackets is supported on the ground (31) and can be screwed there.
- brackets (28) can be used for the fixing (1) stringers to the upper landing (32) that the ladder allows to reach.
- the bracket is placed so that its free wing (29) is oriented vertically and can be screwed flat against the vertical wall (33) against which the staircase is supported.
- brackets (28) For fixing the brackets (28), one can in particular exploit the presence of the groove (27) and / or drill additional holes in the wall of the hollow body (22) and / or the appendage (26).
- the staircase further comprises for each stringer a piece (51), in particular of wood, comprising two faces (52) at right angles and a cylindrical face (53) having the geometric axis l 'edge (54) between the two faces at right angles (52).
- Each face (52) carries a rectangular stud (56) which fits into the hollow body (22) of the stringers.
- a staircase as described so far can be sold as a kit.
- the installer of the staircase according to the invention determines, according to the difference in level and inclination of the staircase he wants to make, the length of the stringers and the number of steps required. He buys two stringers made from section cut to length, and the number of steps desired. Then he climbs, adjusts and fixes the steps, possibly places the sectors then fixes the staircase using the brackets.
- the staircases in the examples described are completely removable and then reinstallable on another site. This is particularly interesting for example for the equipment of construction sites.
- each step is made in two half-steps 61, 62 connected to each other by snap 63.
- the joint thus produced is parallel to the width of the step, it is that is to say perpendicular to the plane of Figure 4.
- An aluminum profile for steps made in one piece would be, because of the large dimensions of its profile, much more expensive to produce than aluminum profiles allowing '' get the half steps.
- the profile of the reverse half has a bulge 64 on its underside. This is useful for increasing the rigidity of the steps when the width of the stairs is relatively large.
- the reinforcement can be provided by a third profile, higher than the half-steps 61 and 62 of FIG. 4, and which, by snap-fastening, is inserted between the half-steps 61 and 62 of the Figure 4, either in all cases or only when it is necessary to make a relatively wide staircase.
- the invention is not limited to the examples described and shown.
- the retaining support between the front hooves and the stringers could be made between the upper face of the anterior guide wing (6) and the adjacent face of the shoe.
- end caps which can be fixed to the ends of stringers for example by fitting into the hollow body, and to each of which is articulated according to a axis parallel to the width of the steps a bracket whose free wing can be fixed against the ground (31) or respectively the vertical wall (33).
