Description

Title of the invention: ONE-PIECE BASE FOR RAILING UPRIGHT, RAILING UPRIGHT AND KIT COMPRISING SUCH A BASE Technical field of the invention

[0001] The present invention relates to a one-piece base for a guardrail post, a guardrail post, and a kit comprising such a base and such a post. It applies, in particular, to the field of guardrails and more specifically to guardrails for technical areas, i.e., areas not accessible to the public. State of the art

[0002] There are several methods of fixing guardrails: - the top-mounted fixing, also called "French style", in which the base for the guardrail post is placed on the surface to be protected, - surface mounting, also called "English style", in which the base for guardrail is placed on a surface perpendicular to the surface to be protected, - offset surface mounting, also called "English style with distance from the wall", similar to surface mounting but in which the base creates a space between the guardrail post and the perpendicular surface on which it is fixed.

[0003] To date, many manufacturers use a specific mounting base for each of the mounting methods mentioned above. Description of the invention

[0004] The present invention aims to remedy all or part of these drawbacks.

[0005] To this end, according to a first aspect, the present invention relates to a base

[0006] monobloc for a guardrail upright having at least one collar, which comprises: - a flat base with at least one fixing hole to a surface against or on which the guardrail post is fixed and - a housing for the amount, between two extensions parallel and perpendicular to the flat base, leading to an opening at one end of the extensions opposite the flat base, each extension having a through hole, the axes of the through holes being coincident; in which the flat base has a so-called "longitudinal axis" and a so-called "generator axis" parallel to the housing and perpendicular to the longitudinal axis, and in which the housing includes at least one groove parallel to the axis of the generatrices formed in at least one extension, each groove being configured to receive a collar of the guardrail post.

[0007] Thanks to these provisions, the guardrail post can be fixed in the French, English, or offset English style, depending on its position within the housing. A bolt positioned through the through holes allows the guardrail post to be locked in place. Furthermore, the collar and groove reinforce the fixing of the guardrail post.

[0008] In embodiments, the housing comprises at least one pair of two grooves parallel to the axis of the generatrices, each positioned on a different extension, the grooves being positioned symmetrically in the housing.

[0009] Thanks to these provisions, the guardrail post and the base can be positioned without constraint of the direction of installation.

[0010] In some embodiments, at least one groove is positioned at the junction between the housing and the flat base. Thanks to these arrangements, a guardrail post having a collar at the end of a profile can be mounted in the base.

[0011] In some embodiments, the dimension of the dwelling along the axis of the generators is equal to the dimension of the housing along an axis normal to the flat base minus the dimension of a groove positioned at the junction between the housing and the flat base.

[0012] Thanks to these arrangements, collars, formed at the ends of the profile of a guardrail post, allow the mounting and holding in position of the post in the base, according to two configurations, French and English style.

[0013] In embodiments, the housing comprises at least two pairs of two grooves parallel to the axis of the generatrices, each groove of a pair of grooves being positioned on a different extension, the grooves of a pair of grooves being positioned symmetrically in the housing, the axis of the orifices passing through the extensions being equidistant from a pair of grooves and the end of the extensions furthest from the flat base.

[0014] Thanks to these provisions, the guardrail post can be positioned offset or not.

[0015] In embodiments, the axis of the orifices through the extensions is at the same distance from the end of the extensions furthest from the flat base as from the edge perpendicular to the axis of the generatrices closest to these orifices.

[0016] Thanks to these arrangements, the same guardrail post collar can, depending on the offset configuration or not, be supported on the ends of the extensions or be held in a groove of the base.

[0017] In embodiments, the dimension of the housing along the axis of the generatrices is equal to the dimension of the housing along an axis normal to the flat base less the dimension of a collar of the guardrail post.

[0018] Thanks to these provisions, when the guardrail post is positioned in the French style, the collars also form a guiding and holding support on both sides of the housing.

[0019] According to a second aspect, the present invention relates to a guardrail upright configured to be fixed to a base which is the subject of the invention, which has a substantially rectangular profile and is provided, at least at one corner of the profile, with a collar.

[0020] In some embodiments, the distance between the axis of a through hole formed in the profile of the upright and an end of the upright is equal to the distance between the axis of the through holes in the extensions and the bottom of the housing closest to the flat base. Thanks to these arrangements, the same guardrail upright collar can, depending on whether it is offset or not, rest on the ends of the extensions or be held in a groove in the base.

[0021] In some embodiments, the width of the profile between two collars formed on the same flat surface of the profile is equal to the dimension of the base between its ends normal to the axis of the generatrices. Thanks to these arrangements, when the guardrail post is positioned in the French style, the collars also form a guiding and retaining support on either side of the housing.

[0022] The purposes, advantages and special characteristics of the guardrail post which is the subject of the present invention being similar to those of the base which is the subject of the present invention, they are not recalled here.

[0023] According to a third aspect, the present invention relates to a kit which includes at least one guardrail upright of the subject of the present invention and at least one base of the subject of the present invention.

[0024] The aims, advantages and special characteristics of the kit subject to the present invention being similar to those of the base subject to the present invention, they are not recalled here. Brief description of the figures

[0037] The present description is given by way of non-limiting grammar, each feature of an embodiment being able to be advantageously combined with any other feature of any other embodiment.

[0038] It is noted from the outset that the figures are to scale but that the scales of the different figures may be different.

[0039] The base of the invention is a truncated cylinder defined between two parallel planes perpendicular to the generatrices of the truncated cylinder. This truncated cylinder is provided with through holes. This truncated cylinder defines a support plate on a flat surface. Throughout this description, the "axis of the generatrices" 25 (see [Fig. 4]) refers to the axis of the generatrices of the cylinder of the base, the "axis normal to the base plate" 26 to the axis perpendicular to the plane of the base support, and the "longitudinal axis" 27 to an axis perpendicular to the axis of the generatrices and to the axis normal to the base plate. These three axes are therefore pairwise perpendicular. The dimensions measured along the longitudinal axis 27 are called "lengths", the dimensions measured along the axis normal to the footing 26 are called "heights" or "depths", and the dimensions measured along the axis of the generatrices 25 are called "widths".

[0040] In [Fig. 1], we observe the directrix of the base 10, two segments of a straight line defining a footing 11, and two extensions 12 and 13 extending perpendicularly to the footing 11, separated by a housing 16. In the embodiment shown in Figures 1 to 5, optional fillets 14 and 15 serve as reinforcement for the extensions 12 and 13, respectively, on the side of the extensions 12 and 13 opposite the housing 16. The housing 16 preferably comprises at least one pair of grooves 17 or 18. In the embodiment shown in Figures 1 to 5, the housing 16 is provided with a groove 17 at its end closest to the footing 11 and a groove 18 substantially in the middle of its depth. The groove 17 is positioned at the junction between the housing 16 and the flat base 11. These two grooves 17 and 18 are configured to receive one of two collars 31 and 32 of a guardrail post 30, collars of a shape corresponding to the grooves (see figures 6 to 8).

[0041] The base 10 is provided with two through holes 21 and 22 on its sole 10 and with two through holes 19 and 20, with axes 23 coinciding and parallel to the longitudinal axis 27, on each of its extensions 12 and 13. Apart from the through holes 19 and 20, the base 10 has: - a symmetry with respect to a plane parallel to the axis of the generatrices 25 and to the axis normal to the sole 26 and - a symmetry with respect to a plane parallel to the longitudinal axis 27 and to the axis normal to the sole 26.

[0042] The offset of the through holes 19 and 20 relative to this last plane and its offset relative to the pair of grooves 18 allows a guardrail post 30 with only one through hole 33 (see figures 3 to 6) to be positioned in three positions: - a "French-style" position, illustrated in [Fig.4], in which the two collars 31 and 32 are each in a plane parallel to the longitudinal axis 27 and to the axis normal to the sole 26 and rest on the symmetrical faces of the housing 16, - an "English-style" position, illustrated in [Fig. 5], in which a collar 31 is housed in the pair of grooves 17 and - an "English-style" position with distance from the wall, illustrated in [Fig.6], in which the other collar 32 is housed in the pair of grooves 18.

[0043] To this end, as illustrated in [Fig.3]: - the distance dl between the axis 23 and the bottom of the housing 16 is greater than or equal to the distance dl' between the axis of the through opening 33 and the lower end of the upright 30, and preferably equal, which allows the lower end of the upright 30 to rest on the bottom of the housing 16, in the "French style" position; - the width d2 of the base 10 is less than or equal to the width d2' between the collars 31 and 32, and preferably equal, which favors the support of the collars 31 and 32 on the edges of the housing 16, in the "French style" position; - the distance d3 between the axis 23 and the plane, perpendicular to the axis 25 of the generatrices, of the base 10 closest to this axis 23 (on the right in [Fig.3]) is equal to the distance d3' between the axis 33 and the inner edge of the collar 31, which favors the support of the collar 31 on this plane, in the "French style" position; - the distance dl between the axis 23 and the bottom of the housing 16 is equal to the distance dl” between the axis of the through orifice 33 and the external end of the collar 32, which allows the insertion of this collar 32 into the pair of grooves 17, in the “English” position »; - the distance d3 between the axis 23 and the upper edge of the housing 16 is less than or equal to the distance d3' between the axis 33 and the inner edge of the collar 31, and preferably equal, which favors the support of the collar on the face of the base opposite the sole 11, in the "English" position; and - the distance d4 between the axis 23 and the upper edge of the grooves 18 is equal to the distance d3' between the axis 33 and the inner edge of the collar 31, which allows the collar 31 to be inserted into the grooves 18, in the "English style with distance from the wall" position.

[0044] It is noted that the term "equal" used above is to be understood with manufacturing tolerances to allow limited mechanical clearances.

[0045] Thus, preferably: - the dimension d2 of the housing 16 along the axis of the generatrices 25 is equal to the dimension of the housing along an axis normal to the flat base 26 less the dimension e of a groove 17 positioned at the junction between the housing and the flat base 11; - the housing 16 comprises at least two pairs, 17 and 18, of two grooves parallel to the axis of the generatrices 25, each groove of a pair of grooves being positioned on a different extension 12, 13, the grooves of a pair of grooves being positioned symmetrically in the housing 16, the axis 23 of the orifices, 19 and 20, which pass through the extensions being equidistant d3 from a pair 18 of grooves and from the end of the extensions furthest from the flat base 11; and / or - the axis 23 of the orifices, 19 and 20, which cross the extensions 12, 13 is at the same distance d3 from the end of the extensions furthest from the flat base 11 as from the edge perpendicular to the axis of the generatrices 25 closest to these orifices 19 and 20.

[0046] The embodiment illustrated in Figures 1 to 11 exhibits all the preferred equalities described above. Of course, in other embodiments not shown, only some of these preferred equalities are satisfied.

[0047] Screws (not shown) secure the base to a support (not shown), either horizontal (in the case of "French-style" mounting) or vertical (in the case of "English-style" mounting). A bolt 34 passes through the through holes 19, 20 and 33 and secures the upright 30 to the base 10.
