Definitions
- This invention concerns a staircase module positioner tool whose obvious purpose is to regulate the depth of each step, the verticality of the step riser or rear wall, and the difference in level between steps, all drawn from the horizontal plane of the first step.
- the positioner tool herein invented may be used to obtain step depth, the verticality of the step's riser or rear wall, and the difference in level between said first step plane and the next step plane which will lie parallel to the first, serving as a reference for all following step planes.
- the tool also works to fix the distance between the edge of the first step and the edges of following steps in vertical projection so that an exact number of modules will fit in between the bottom of the first step and the edge of the plane to which the staircase leads.
- the aim is to maintain a constant step height and depth in a staircase of a given height and projection, while the depth and height of each step will be the result of dividing the height and projection exactly by the same number.
- Staircase designing begins by calculating to find the number of steps, their height and their depth. First a master ramp is laid out. This ramp may be arched, and it serves as a foundation so that the bore of the staircase itself can be roughed out and later covered with slabs or prefabricated components and thus finished.
- Document DE-A-8609211 discloses an staircase positioner tool with different embodiments according to the way it is aplied to different kind of steps or to the same kind of step. In all these cases, it is only posible with this tool to regulate the verticality of the riser and the depth of the step, but it doesn't incorporate fixing means that provides the accuracy required when it is used on the steps, and it has not the auditority to regulate the right extent of the lip of the step.
- the tool proposed herein is a positioning device that guarantees perfect staircase modularity, that is, that step height and risers will always be uniform so that exact precision will exist throughout, from the bottom to the junction where the staricase's projection meets the upper floor.
- the tool herein invented operates by drawing on the horizontal plane of the first step, which is hand-laid by the specialist. Using the horizontal plane of this first step, step depth, the verticality of the riser or rear wall of the step and the difference in level between said first step plane and the next plane may be exactly regulated, one after another.
- each step plane will serve as the reference for the next plane, up to crown of the staircase, which will lie perfectly flush with the plane of the upper floor.
- the device is comprised of what may be considered two transversal racks, joined parallel to one another by a telescoping intervening longitudinal bar whose length may be adjusted to lengthen or shorten the distance between these two racks to match the length of the steps, or rather the width of the step.
- Each of the aforesaid racks features a surface designed to rest on the edge of the slab forming the horizontal plane of the first step, and a right-angle elbow bend at the other end, on which are mounted resting surfaces for positioning the step riser.
- Each of these right-angle elbow bends and the regulable components coupled to them constitutes a continuation, which are equipped in turn with an attachment which has the triple function of holding up the slab forming the plane for the next step, correcting the verticality of the riser slab, and marking the amount that the next step plane slab will have to protrude in order to make for precision in the building module.
- the surfaces for the edge of the first step's slab to rest upon are also equipped with attachement clips worked by screw spindles, which may be hand-cranked to grip the edge belonging to the first step plane.
- the slab or master slab that is going to constitute the horizontal plane of the first step will be set in place by hand, and after it is correctly leveled, the planned projection will jut out from its skirt (here skirt is taken to mean the first riser).
- the extendible longitudinal bar affixed to both of the transversal racks that form the aforementioned resting surfaces will ensure the correct parallel coplanar placement in any relative instance betweeen the maximum and the minimum; that is the transversal racks will alawys lie in the perfect flat position.
- the longitudinal bar may be complemented with a hinge or circular sector which may be fixed to one of the racks to allow those stairs that swivel 90 o or follow a curved path to be arranged in modules along their angle or curve.
- FIG. 2 This illustration provides an overall perspective of the positioner tool in its operating position, that is, set up on the slab forming the horizontal plane of a bottom step and the riser or rear vertical wall of that same first step.
- a conventional staircase (1) is formed of a number of steps constituted by horizontal planes (2) which may, for example, be slabs. These slabs jut forward forming projections (3), while at the rear these horizontal planes (2) are complemented with vertical risers (4) which are also made up of slabs or any other suitable material.
- the total projection of the staircase is equal to the distance between the bottom point (6) of the staircase and its junction (7) with the upper floor (8).
- the total height of the staircase must be an exact multiple of a module, which is the exact distance between two horizontal planes (2) or steps; while the projection of the staircase must be an exact multiple of another module, which is the same as the distance between two consecutive vertical risers (4), or in other words, the distance between the riser of each step and the corresponding skirt of the first plane (2) of the step.
- the number of modules coincides in height and risers, and thus the staircase is perfect.
- FIG 1 which clearly shows the positioner tool in place on a first step.
- This step is made up of the slab (2) forming the step's horizontal plane, featuring the bottom point (6) and the skirt (11) of this starting step, which corresponds with the vertical risers (4) of the following steps.
- the device as such is made up of a pair of twin racks (12) joined by a telescoping longitudinal bar (13), which is formed by two telescoping spans which may be held by a transversal screw (32) in such a way that the longitudinal bar (13) may be used to shorten or lengthen the distance between these two racks (12), depending on the width of the staircase or, in other words, the width of the step.
- the racks (12) are lain transversally, as shown in figure 2, and each of them includes a resting surface (14) that lies against the forward edge (15) of the slab (2).
- This resting surface (14) is complemented by a clamp (16) worked manually with a crank (17) that turns a screw spindle in the clamp (16), so the two clamps, one on each surface, form a means of gripping the forward or front edge (15) of the slab (2).
- each rack (12) On the end lying opposite the resting surface (14), each rack (12) has continuations (18) which bend at a right angle, each forming a vertical span (19) on which is mounted a telescoping element (20) whose extensibility may be regulated and which may be anchored with a screw (21).
- the tool is placed on the first step slab (2), as depicted in figure 2, with its surfaces (14) resting on the front edge (15) of this slab (2).
- the length of the racks (12) is then adjusted, thus finding the depth that the continuations (18) will have to reach, while the upper part (22) of the elements (20) that may be extended from the elbow spans (19) of these continuations (18) will form the seat for the projection of the second slab (2), belonging to the next step, thus forming the horizontal module (12) depicted in figure 1.
- the clamps (16) are used to immobilize the tool assembly by gripping the front edge of the slab (2) in question so that the next riser slab (4) will be automatically positioned to rest on the surface formed by the vertical spans (19) and (20) of the elbow continuations (18).
- the correction or precision of the exact vertical line traced by the riser slab (4) will be determined by turning the stem (21), while the top slab's front edge (15) is positioned using the regulable stops (23), thus regulating their own projection over the riser or vertical slab (4).
- a slide housing (24) for each arm (25) is designed into one or both regulable stops (23).
- the arms (25) have an upper stop face (26) indicating the position of the side edge (27) of the slab (2).
- These arms (25) also include a square (28), which is also regulable and is for positioning the outer edge of the riser tablet (4) when the staircase has a cambered or face string. As is logical, this device is used in duplicate, one at each side, when the staircase rises with both sides open.
- the arms (25) may be regulated inside their slide guides (24) and immobilized using the correct screws (29), like the squares (28), which may be immobilized with their own screws (30).
- the longitudinal bar (13) includes a compass (31) that is extremely important in making curved or turning staircases and is essential in cases in which the stair case is winding or runs along a curved or continuous path.
- the positioner tool referred to above may be used on the horizontal plane (2) of the first step to obtain the step depth, the verticality of the riser slab (4) for that step, and the difference in level between that first horizontal step plane and the net horizontal plane, which will lie parallel to the first and will serve as a referene for all following step planes until the difference in level between the base plane and the upper floor (8) has been covered.
- the device herein invented may be used to find the projection between the edge (15) of the slab (2) and the plane of the riser slab (11), maintaining the distance of the riser slabs (1) in accordance with the module.
