Description

The invention relates to a shoe for self-supporting guardrail and a self-supporting railing for construction work, including roof-terrace type, comprising such a shoe.

The term guardrail means a set of elements forming a protective barrier. A self-standing railing is a guardrail that is not permanently attached to a construction structure but is ballasted on the construction work to prevent any tipping. This type of self-supporting railing is very advantageous especially for a quick and inexpensive assembly / disassembly and to ensure the tightness of the construction work by avoiding damage to the support surface of the guardrail.

In known manner, the guardrails for roof terrace are installed around the perimeter of the terrace. Most known guardrails typically include a plurality of substantially vertical posts that support a plurality of substantially horizontal rails. The term "vertical element" means any element substantially perpendicular to the ground and the term "horizontal element" any element substantially parallel to the ground. Each upright is supported in the lower part by a shoe, each shoe resting on the construction work and having a support mast in which is provided an enclosure, said support mast receiving a lower end of the amount concerned. As known in the field of self-supporting railings, in particular FR2960249 A1, FR2939461 A1 or EP2525015 A1 documents, the shoe further has a base defining an enclosure formed along a longitudinal axis of the base. The enclosure of the base receives a first end of an offset arm, said offset arm being equipped at its second free end with at least one ballast element.

However, this known type of shoe for self-supporting railing has the disadvantage of offering only one configuration for the positioning of the offset arm, namely an offset arm which extends from the shoe in a direction along the longitudinal axis of the base, generally towards the interior of the structure. The ballasting is then carried out only on one side of the shoe, the one where extends the arm of offset, which is far from being reassuring especially in certain roof terrace configurations. In addition, the known hooves are made in one piece, offering no flexibility to the installer to adapt to the specific constraints of the construction work, whether in relation to the weighting of the guardrail 10 freestanding or in relation to the amount of the free-standing railing. The object of the invention is to remedy all or some of the aforementioned drawbacks. The subject of the invention is a self-supporting railing shoe comprising a support mast for receiving an upright and a base for receiving an offset arm, characterized in that the base has a first opening and a second access opening opposite to the first access opening, the first access opening and the second access opening being each shaped to receive an offset arm. Thus, the shoe according to the invention, having two opposite access openings, can accommodate at least one offset arm in three configurations: a first configuration in which the offset arm extends substantially entirely from a first side of the shoe, being engaged only in the first access opening, - a second configuration in which the offset arm extends substantially entirely from a second side of the shoe opposite the first side, being engaged only in the second access opening, - a third configuration in which two offset arms or two portions of the same deposition arm extend on both sides of the shoe, on either side of the support mast, which allows a weighting railing on both sides of the railing, thus significantly improving the stability of the self-supporting railing.

In addition, this shoe allows to offer several configurations for ballasting, thus offering the flexibility that is not achieved for the hooves of the state of the prior art.

According to a characteristic of the invention, the first access opening and the second access opening form a lower enclosure passing right through said base for receiving said offset arm. Thus, one can thus use a single offset arm for all of the above configurations.

Advantageously, the lower enclosure passing right through the base is shaped to receive the offset arm by sliding. According to the invention, the base is a profile of constant section. According to another characteristic of the invention, the support mast has an upper enclosure intended to receive the upright, said upper enclosure of the support mast extending substantially perpendicularly with respect to the lower enclosure of the base. According to another characteristic of the invention, the support mast is a profile, said support mast extending substantially perpendicular to the base. According to the invention, the support mast is a section of constant section. According to another characteristic of the invention, the support mast is removably attached to the base. Advantageously, the support mast is removably joined to the base by means of at least one connecting member, which is for example a self-tapping screw. According to another characteristic of the invention, the support mast is provided with at least one orifice receiving a wedging member intended to press the upright inside the support mast. According to another characteristic of the invention, the base is provided with at least one opening opening into the lower chamber, said at least one opening being intended to receive a wedging member intended to press the offset arm to inside said base. Preferably, the orifices receiving a wedging member are threaded. In addition, the wedging members are preferably pressure screws. According to another characteristic of the invention, the base is provided with two orifices disposed on either side of the support mast, said two orifices being intended to each receive a wedging member. Preferably, the wedging member is a set screw. According to another characteristic of the invention, the base has an upper face on which the support mast rests, and an opposite lower face widened with respect to the upper face. The enlarged underside allows the shoe to be more stable since the bearing surface is increased. Preferably, the enlarged lower face of the base is provided with a pad. Advantageously, the pad has a peripheral rim for hooking the pad on the base. Preferably the peripheral flange is open at at least one of the access openings of the base to accommodate a base longer than the length of the pad. According to another characteristic, the support mast is equipped with an open cap positioned on the free end of the support mast. The cap is shaped to plug the perimeter of the support mast profile while leaving the upper enclosure of the support mast open. Thus, the sealing of the support mast is improved. The invention also relates to a self-supporting railing 35 comprising at least one shoe according to the invention, wherein an amount is supported by the support pole of said shoe and an offset arm is slidably mounted inside the shoe. the lower enclosure of the base, said offset arm being designed to be equipped with at least one ballast element. Advantageously, the offset arm is equipped with at least one ballast element at one of its ends.

The invention will be better understood, thanks to the following description, which relates to at least one embodiment according to the present invention, given by way of non-limiting example and explained with reference to the appended diagrammatic drawings, in which: FIG. 1 represents an exploded perspective view of a shoe according to the invention; FIG. 2 shows a partial perspective view of a mounting detail of the shoe represented in FIG. 1; FIG. section of a self-supporting railing according to the invention, - Figure 4 shows a top view of the mat of the shoe shown in Figure 1 and 2, - Figure 5A shows a first configuration of self-supporting railing according to the invention FIG. 5B represents a second configuration of the self-supporting railing according to the invention; FIG. 5C represents a third configuration of the self-supporting railing according to the invention, and FIG. no variant of the third configuration shown in FIG. 5C.

According to the invention, the shoe 1 for self-supporting railing 10 comprises a base 3 and a support pole 2 removably assembled. The base 3 and the support mast 2 are sections of constant section, as shown in Figures 1 to 3, 5A, 5B, 5C and 5D.

As shown in Figure 2, the support mast 2 is assembled with the base 3 by two connecting members 9b, in this case two self-tapping screws.

In the example illustrated in FIG. 1, the base 3 comprises a through-going enclosure 5 and comprising two opposite access openings 5a and 5b, the access opening 5b being visible in FIG. 2. The base 3 comprises a face lower 3b and an upper face 3a. The upper face 3a receives one of the faces of the support mast 2. The lower face 3b receives a shoe 4. In Figures 1, 2 and 3, the lower face 3b is enlarged, and has a surface greater than the upper face 3a. As can be seen in FIG. 1, the pad 4 comprises an open peripheral rim. The opening of the flange corresponds to the access opening 5a, which accommodates a base 3 of a length greater than the length of the pad 4. The pad 4 is clipped to the base 3 in the example illustrated. According to the invention and as represented in FIGS. 1 and 4, the support mast 2 comprises an upper enclosure 6 intended to receive an upright 11 of a self-supporting railing 10.

Visible in Figure 1, two orifices 8 are provided on the support mast 2. These holes 8 each cooperate with a wedging member 9a. In addition, two orifices 8 are also provided on either side of the support mast 2 on the base 3. These orifices 8 are intended to cooperate each with a wedging member 9a. The wedging members 9a, which are, for example, setscrews, allow the support and the wedging of the upright 11 intended to slide in the upper enclosure 6 of the support mast 2 or of the offset arm 13 intended to slide in the lower enclosure 5 of the base 3. As can be seen in Figures 1, 2 and 4, the support mast 2 has a curved face shaped to receive a skirting attachment, the curved face having on both sides a protruding portion retaining 30 forming a rail for receiving a baseboard fastener. This form is described more particularly in patent applications FR2975452 A1 and FR2525015 A1. Of course, the invention is not limited to this example and the support mast of the invention may be devoid of this particular form. In FIG. 4, the support mast 2 is shown in plan view. As said before, one of the faces is curved and is shaped to receive a skirting attachment, the other faces are straight. Two orifices 8 are formed on either side of the upper enclosure 6. These orifices 8 are intended to receive connecting members 9b shown in FIGS. 2 and 3. The upper enclosure 6 comprises projecting portions of wedges 16 allowing to guide the sliding of the upright 11 and to wedge the upright 11 once in the upper enclosure 6. The orifices 8 are threaded in the example, according to the invention it is also possible that the orifices are smooth. As can be seen in FIG. 3, the base 3 receives in the lower enclosure 5 an offset arm 13. As for the upper enclosure 6, the lower enclosure 5 is provided with projecting portions 15 for guiding the sliding of the offset arm 13. In addition, it can be seen that the wedging member 9a bears against the offset arm 13 which is thus immobilized.

FIGS. 5A, 5B, 5C and 5D represent the various possible configurations of the self-supporting railing 10 thanks to the shoe 1 according to the invention.

Thus, in FIG. 5A, is represented the configuration according to which the offset arm 13 is received by the access opening 5a and extends in a direction substantially perpendicular to the direction in which the post extends, and this towards the interior of the construction work (not shown). In this configuration, a weighting element 14 is positioned at the free end of the offset arm 13, the other end of the offset arm 13 being housed in the enclosure 5 of the base 3. In FIG. 5B, is represented a configuration in which one end of the offset arm 13 is housed in the access opening 5b and the other end is equipped with a ballast element 14. In this configuration, the offset arm 13 extends in a opposite direction to that shown in Figure 5A, namely to the outside of the structure. Figures 5C and 5D show two configurations in which a ballast on either side of the shoe 1 is made.

In FIG. 5C, an offset arm 13 passes through the lower enclosure 5 of the base 3 and is ballasted at its ends by a weighting element 14. Of course in this configuration it is possible for there to be two offset arms 13 each slidably introduced into a different access opening 5a, 5b and extending in opposite directions. In FIG. 5D, the offset arm is equipped with more than two weighting elements 14. The weighting elements 14 are shaped to receive the offset arm in a through manner.

As can be seen precisely in FIGS. 5C and 5D, the base equipped with opposite access openings 5a, 5b makes it possible to adapt the length of the offset arm (s) 13 as a function of the construction work and the place to put the self-supporting railing 10.

Of course, the invention is not limited to the embodiment and the embodiments described and shown in the accompanying figures. Modifications are possible, particularly from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.
