Description

Title of the invention: Guardrail and railing kit

[0001] The present invention relates to the field of guardrails used in buildings to ensure the safety of people located on elevated structures, such as roofs or terraces.

[0002] Generally, a guardrail system extends along the edges of a roof or terrace, and comprises a plurality of successive vertical posts which are attached to the structure by means of brackets of the system which can be screwed onto it.

[0003] The guardrail device also includes a top rail attached to the upper ends of the uprights and forming a handrail, and one or more intermediate rails arranged under the top rail.

[0004] Conventionally, the upright is fixed to the associated shoe by screwing to prevent any vertical movement of the upright after assembly.

[0005] This requires a number of important operations to assemble the guardrail device, and necessitates the need for tools.

[0006] The present invention aims to remedy these drawbacks.

[0007] More particularly, the present invention aims to provide a guardrail kit that is easy to manufacture and install.

[0008] The invention relates to a guardrail kit intended to be installed on a structure, in particular on a building roof or terrace, the kit comprising:

[0009] - a shoe having a lower wall and at least one upper wall or internal, equipped with a vertical through-hole, and

[0010] - an amount mounted removably between a locked position at the shoe in in which the lower end of the upright extends through the through opening of the shoe and enters a disassembly position in which the upright is separated from the shoe.

[0011] According to a general feature, the through opening of said upper or internal wall is shaped to allow the lower end of the upright to be introduced inside the shoe in an unlocked position of the upright relative to the shoe, and to allow at least the rotation of the upright from this unlocked position to the locked position in a first direction of rotation.

[0012] According to another general feature, in the locked position of the upright, a part of said upper or internal wall of the shoe protrudes inside a slot formed in the thickness of the upright, said part remaining away from the upright in the unlocked position.

[0013] According to a first conception, in the locked position of the upright, said part cooperates by contact with an edge of the slot to obtain the vertical upward locking of said upright relative to the shoe.

[0014] According to a second design, in the locked position of the upright, said part cooperates by contact with an edge of the slot to obtain the rotational blocking of said upright relative to the shoe at least in a second direction of rotation opposite to the first direction of rotation.

[0015] Thus, after inserting the upright into the shoe, the upright can be locked in place without the need for any screwing operations. The kit can therefore be assembled manually without tools.

[0016] The movement of the component from its unlocked position to its locked position can be achieved by rotating it counterclockwise. Alternatively, it is possible to rotate it clockwise to achieve this movement to the locked position. The rotation can be a few degrees, for example, from 5° to 15° as an example.

[0017] In one embodiment, the slot of the upright includes at least a horizontal part inside which protrudes the part of said upper or internal wall of the shoe in the locked position of the upright, said part cooperating by contact with a lower edge of the horizontal part of the slot to obtain the vertical upward locking of said upright relative to the shoe.

[0018] In another embodiment, the slot of the upright includes at least one vertical part inside which protrudes the part of said upper or internal wall of the shoe in the locked position of the upright, said part cooperating by contact with a lateral edge of the vertical part of the slot to obtain the rotational locking of said upright relative to the shoe in the second direction of rotation.

[0019] The slot can be opened outwards in the horizontal direction. Alternatively, the slot can be opened outwards in an oblique direction.

[0020] Preferably, the slot in the upright is through-hole. This may be the case, in particular, when the upright is in the form of a hollow profile. Depending on the cross-section of the upright, it is also possible to provide a blind slot.

[0021] According to a first conception, the shoe is provided with the upper wall and the inner wall, the upper wall being provided with said through opening. The inner wall may, for example, extend obliquely between the lower and upper walls and be connected to at least one of said walls.

[0022] According to a second alternative design, the shoe can be devoid of the inner wall.

[0023] According to a third alternative design, the shoe is provided with the upper wall and the inner wall, each of said walls being provided with a through opening as defined previously.

[0024] According to another alternative design, said through opening is provided on the inner wall independently or not of the presence of the upper wall.

[0025] Preferably, the shoe is provided with at least one vertical wall having a through opening, the kit further comprising a strut mounted removably between a mounted position on the shoe in which the strut extends horizontally and through said through opening, and a disassembly position in which the strut is separated from the shoe.

[0026] Advantageously, the kit further includes at least one ballast block mounted on the strut on the side of its free end in the position where it is mounted on the bracket. After the kit is installed, the ballast block(s) mounted on the strut ensure that it is locked in place.

[0027] Advantageously, in its mounted position, the strut abuts against the upright in its locked position. Thus, after the kit is installed, the strut prevents any unwanted rotation of the upright from its locked position to the unlocked position.

[0028] The shoe may be provided with external vertical side walls connecting to the lower and upper walls, one of the external side walls being provided with said through opening through which the strut extends in its mounted position.

[0029] The shoe may further include an internal vertical stiffening wall extending between the lower and upper walls and connected to said lower and upper walls, the internal stiffening wall being provided with a through opening through which the strut extends in its mounted position.

[0030] The invention also relates to a guardrail comprising a plurality of kits as defined above, a top rail extending horizontally and connected to the top ends of the kit uprights, and at least one intermediate rail extending horizontally, connected to the kit uprights and located vertically below the top rail.

[0057] Figure 1 shows a partial representation of a guardrail 10 which is in position installed. The guardrail 10 can, for example, be installed on the flat roof of a building or industrial site, or on a terrace to prevent falls, or even in a work area to be delimited. In this example, the guardrail 10 is self-supporting.

[0058] The guardrail 10 comprises a plurality of guardrail kits 12, and a top rail 14 and an intermediate rail 16 attached to the kits. For reasons of re In the presentation, only three kits 12 were illustrated in [Fig. 1]. It is easy to understand that the number of kits 12 can be adapted according to the size of the area to be secured.

[0059] As more clearly illustrated in Figures 2 and 3, each kit 12 comprises a base or shoe 18, and an upright 20 and a strut 22 mounted on the shoe. The shoe, the upright 20 and the strut 22 can be made of metal, composite material or synthetic material.

[0060] The upright 20 is mounted removably relative to the shoe 18 between a locked position on the latter illustrated in figures 5 to 10 in which vertical movement is blocked, and a dismantling position (figures 15 and 16) in which the upright is separated from the shoe.

[0061] As will be described in more detail later, the upright 20 is movable in rotation relative to the shoe 18 to move from an unlocked position (figures 2 to 4) in which it is not fixed to the shoe to the locked position, and vice versa.

[0062] Referring to Figures 3 and 4, the shoe 18 comprises a lower wall 24 intended to bear against the roof, and an upper wall 26 vertically opposed to the lower wall 24. The lower wall 24 and upper wall 26 define the overall height of the shoe. The lower wall 24 is flat. In the illustrated embodiment, the upper wall 26 has a stepped shape. Alternatively, a flat shape may be provided for the upper wall 26.

[0063] The shoe 18 comprises first and second external side walls 28, 30, each connecting to the lower wall 24 and upper wall 26. The side walls 28, 30 extend vertically. The side walls 28, 30 define the longitudinal dimensions of the shoe. The side wall 28 of the shoe is designed to bear against a parapet of the structure on which it is mounted, or against a plinth thereof.

[0064] In the illustrated embodiment, the shoe 18 is open in the transverse direction for manufacturing simplicity. Alternatively, the shoe 18 could be closed and in this case equipped with longitudinal walls connecting to the lower walls 24, upper walls 26 and the side walls 28, 30.

[0065] As illustrated more visibly in figures 11 to 13, the shoe 18 comprises an internal stiffening wall 32 extending obliquely between the upper wall 26 and the lower wall 24. The internal wall 32 is connected on one side to the upper wall 26, and on the other side to the junction area between the lower wall 24 and the external side wall 28.

[0066] The shoe 18 further includes an internal stiffening wall 34 extending vertically between the internal wall 32 and the lower wall 24 and being connected to said walls.

[0067] In the embodiment shown, the shoe 18 also includes an internal stiffening wall 36 extending vertically between the upper wall 26 and the lower wall 24, being connected to said walls. The internal wall 36 is offset from the internal wall 34 on the side of the external lateral wall 30.

[0068] To allow the upright to be mounted on the bracket 18, a through opening 40 is provided in the thickness of the upper wall 26 of the bracket. The opening 40 passes through the upper wall 26 in the vertical direction.

[0069] The section of the opening 40 is larger than that of the upright. The opening 40 is shaped to allow the lower end of the upright to be inserted into the shoe 18 in its unlocked position, and to allow the upright to be rotated from this unlocked position to the locked position.

[0070] As will be described in more detail later, the opening 40 is also shaped to obtain, in the locked position, the blocking of the upright relative to the shoe 18 by contact with the upper wall 26 thereof.

[0071] As can be seen in [Fig. 14], the opening 40 comprises a main part 42 and an extension 44 extending laterally outwards from the main part 42. In [Fig. 14] dashed lines have been added in the opening 40 to schematically represent the main part 42 and the extension 44.

[0072] The section of the main part 42 of the opening is generally similar in shape to that of the upright, and here has a generally oblong shape. The section of the main part 42 of the opening is at least equal to that of the upright and preferably slightly greater to facilitate its insertion into the shoe 18. The dimension of the major axis of the main part 42 may, for example, be greater by about 1% to 5% than that of the upright 20, and the dimension of the minor axis of the main part 42 may, for example, be greater by about 20% to 30% than that of the upright 20.

[0073] In the illustrated embodiment, the opening 40 is provided with two opposing longitudinal edges 40a, 40b, and two opposing lateral edges 40c, 40d which connect to the longitudinal edges 40a, 40b. The longitudinal edge 40b has a stepped shape with a first section 40b, a second section 40b2, and a connecting section 40b3 which links the first and second sections.

[0074] The lateral edges 40c, 40d, the longitudinal edge 40a and the second section 40b2 of the longitudinal edge 40b define the main part 42 of the opening. The first section 40bi and the connecting section 40b3 define the extension 44 of the opening.

[0075] Referring now to Figures 15 to 17, the upright 20 is in the form of a tubular profile. The upright 20 is shown here in a purely rectilinear shape. Alternatively, the upright 20 could have a straight section extended by an oblique section extending upwards. The upright 20 is shown here in cross-section as a oblong shape. Alternatively, other shapes are possible, for example rectangular, square, circular.

[0076] In the embodiment shown, the upright 20 has two opposing flat main faces 20a, 20b, and opposing front faces 20c and rear faces 20d that connect to the main faces 20a, 20b. The front face 20c and rear face 20d are rounded. When mounted on the bracket 18, the rear face 20d is oriented towards the side of the strut 22 and the front face 20c is oriented towards the opposite side.

[0077] A through slot 46 is provided in the thickness of the upright. The slot 46 extends horizontally along the upright 20. In this embodiment, the slot 46 consists of a single horizontal portion 47.

[0078] Slot 46 is horizontally through-hole. Slot 46 opens into the inside of the upright. Slot 46 is formed on the front face 20c of the upright. On the front face 20c, slot 46 is offset from the side of the main face 20a. In the illustrated embodiment, slot 46 extends horizontally from the main face 20a to slightly beyond the midpoint of that face.

[0079] The slot 46 is formed in the thickness of the front face 20c. The slot 46 is delimited vertically by two opposing upper and lower edges 46a, 46b, which are spaced apart and facing each other. In the illustrated embodiment, the edges 46a, 46b are straight and extend horizontally. The slot 46 is delimited horizontally by two opposing lateral edges 46c, 46d that connect to the edges 46a, 46b.

[0080] As will be described in more detail later, in the locked position of the upright, the slot 46 of the upright cooperates with the upper wall of the shoe. The height of the slot 46 is slightly greater than the thickness of the upper wall of the shoe.

[0081] In the illustrated embodiment, a through-hole 48 is formed at the lower free end of the upright 20. The hole 48 is provided on the front face 20c of the upright. The slot 46 is located vertically above the hole 48.

[0082] As illustrated in [Fig. 3], the main portion 42 of the opening in the shoe 18 allows the lower end of the upright 20 to be inserted into it in its unlocked position. The upright 20 is inserted into the shoe 18 by sliding vertically from top to bottom until it comes into contact with the lower wall 24 of the shoe. In this unlocked position, the upright 20 can be freely moved vertically upwards relative to the shoe 18. In this position, the main face 20a, and more generally the upright 20, remains at a distance from the longitudinal edge 40b of the opening. When inserting the upright 20 into the shoe 18, the longitudinal edge 40a ([Fig. 4]) of the opening can be used to guide the upright vertically, and more specifically, the main face 20b.

[0083] The shape of the opening 40 in the upper wall of the shoe allows the upright to be rotated a few degrees around a vertical axis from its unlocked position to reach the locked position. In the illustrated embodiment, the transition from the unlocked to the locked position is achieved by counterclockwise rotation. Alternatively, it could be possible to shape the opening 40 to allow the upright to be moved from the unlocked to the locked position by clockwise rotation.

[0084] As illustrated in particular in Figures 6 and 9, in its locked position, the upright 20 rests against the longitudinal edge 40b of the opening 40 of the shoe. The main face 20a of the upright rests against the longitudinal edge 40b. More precisely, the upright 20 rests against the first section 40bi ([Fig. 14]) of the longitudinal edge 40b.

[0085] In the locked position of the upright 20, given the stepped shape of the longitudinal edge 40b, a portion of the upper wall 26 of the shoe extends inside the slot 46 (Figures 16 and 17) through the upright. This portion of the upper wall 26 is provided with the second section 40b2 and the connecting section 40b3. This portion of the upper wall 26 is referred to as 49 in [Fig. 14].

[0086] This part of the upper wall 26 protrudes inside the slot 46 of the upright in the locked position as illustrated in particular in Figures 6 and 8, and remains at a distance from the upright in the unlocked position as illustrated in particular in [Fig.3].

[0087] In the locked position of the upright 20, upward vertical movement is blocked by the contact between this portion 49 of the upper wall 26 of the shoe and the lower edge 46b of the slot in the upright ([Fig. 8]). More precisely, upward vertical movement is blocked by the contact between the lower face of this portion 49 of the upper wall 26 of the shoe and the lower edge 46b of the slot. In this position, the upright 20 is fixed against the shoe 18 in translation.

[0088] As previously stated, the shoe 18 includes the internal stiffening wall 32, which is particularly visible in Figures 7 and 11. A through opening 50 is provided in the thickness of the internal wall 32 of the shoe. The opening 50 passes vertically through the internal wall 32. The opening 50 is provided in the vertical extension of the opening 40 in the upper wall 26 of the shoe.

[0089] The opening 50 is also dimensioned to allow the lower end of the upright 20 to be inserted into the shoe in its unlocked position, and to allow the upright to rotate from this unlocked position to the locked position. Unlike the opening 40, the opening 50 is not shaped here to lock the upright in its locked position by cooperating with it.

[0090] Alternatively, the opening 50 could be shaped to achieve this locking. In this case, a second slot would need to be provided on the upright 20 vertically below the slot 46 in place of the clearance 48. In the illustrated embodiment, the clearance 48 is provided on the upright 20 to prevent interference between the inner wall 32 of the shoe and the upright 20 during its rotation from the unlocked position to the locked position, and vice versa.

[0091] With reference to Figures 11 to 13, each of the external side walls 30 and internal walls 36, 34 includes a through opening 52, 54, 56 formed in its thickness for the passage of the strut in its mounted position. Each opening 52, 54, 56 passes horizontally through the associated wall. The openings 52, 54, 56 are aligned horizontally.

[0092] As illustrated in [Fig. 7], in its mounted position, the strut 22 extends horizontally and through the through openings 52, 54, 56 of the shoe. The free end of the strut 22, located inside the shoe 18, bears against the upright 20 in its locked position. The free end of the strut 22 also bears against the rear face 20d of the upright. The strut 22 is removably mounted between the mounted position and a disassembled position (not shown) in which it is separated from the shoe 18. The strut 22 is in the form of a tubular profile.

[0093] Referring again to [Fig. 1], each kit 12 also includes ballast blocks 60 mounted on the strut 22 on the free end side located outside the shoe 18. The ballast blocks 60 are here two in number and stacked. Alternatively, it could be possible to provide a single ballast block 60, or even a greater number of ballast blocks, stacked or not.

[0094] The installation of the guardrail 10 can be carried out in the following manner.

[0095] In a first step, the shoe 18 of each kit 12 is put in place against the parapet of the terrace or roof, or the plinth attached to it, with a predetermined center distance between two successive 18 brackets.

[0096] Next, in a second step, the upright 20 of each kit 12 is inserted vertically into the associated bracket 18 in its unlocked position until it rests against the lower wall 24 of the bracket. From this position, the upright 20 is rotated relative to the bracket 18 around a vertical axis of rotation to bring it into its locked position. The upright 20 is thus secured to the bracket 18.

[0097] Then, in a third step, the strut 22 of each kit 12 is introduced horizontally into the shoe 18 to bring it into contact against the lower free end of the associated upright 20 which is locked.

[0098] Next, in a fourth step, the ballast pads 60 are positioned on the strut 22 from each kit 12.

[0099] Finally, in a fifth step, the intermediate rail 16 and the upper rail 14 are installed and fixed to the uprights 20 of the kits 12. The intermediate rail 16 and upper rail 14 extend horizontally and transversely with respect to the uprights 20.

[0100] In the embodiment described above, the kits 12 are designed to provide a self-supporting guardrail 10. Alternatively, kits 12 with a slightly different design can be used to obtain other types of guardrails.

[0101] For example, in the embodiment illustrated in [Fig. 18], where identical elements bear the same reference numerals, the bracket 18 is designed to allow it to be fixed flat on the structure to be secured. This is generally referred to as French-style mounting.

[0102] The shoe 18 of this kit differs mainly from the previous embodiment in that the lower wall 24 is further provided with two lateral lugs 24a, 24b arranged on either side of the shoe, allowing it to be fixed, for example, by screwing. In this example, the upper wall 26 of the shoe is flat.

[0103] In the embodiment illustrated in [Fig. 19], where the identical elements bear the same reference numerals, the bracket 18 is designed to allow its surface mounting on the structure to be secured. This is generally referred to as English-style mounting.

[0104] The shoe 18 of this kit differs mainly from the first embodiment in that the side wall 28 is further provided with two lateral lugs 28a, 28b arranged on either side of the shoe, allowing it to be fixed, for example, by screwing. In this example, the upper wall 26 of the shoe is flat.

[0105] In these two embodiments, kit 12 is without a strut given its method of attachment to the structure to be secured.

[0106] The embodiment illustrated in figures 20 to 25, on which the identical elements bear the same references, differs from the first example in that the locking of the upright 20 relative to the shoe 18 is carried out by a rotation followed by a downward translation of the upright.

[0107] As can be seen in particular in [Fig. 24], in this example, the upper wall 26 of the shoe is equipped with a locking finger 70 that projects inside the opening 40. The finger 70 extends horizontally. The finger 70 is located here in the area where the longitudinal edge 40b connects to the lateral edge 40d. In this example, the longitudinal edge 40b of the opening is straight.

[0108] Referring now to [Fig. 25], in this example, the slot 46 of the upright further comprises a vertical part 72, extending vertically upwards the Horizontal section 47. Horizontal section 47 is shortened here. Vertical section 72 extends horizontal section 47 along the side of the lateral edge 46d, which is located on the opposite side of the main face 20a. Vertical section 72 extends the upper edge 46b of horizontal section 47.

[0109] Similar to the horizontal portion 47, the vertical portion 72 is formed within the thickness of the upright and extends horizontally. The vertical portion 72 is delimited horizontally by two opposite lateral edges 72a, 72b, which are spaced apart and aligned. In the illustrated embodiment, the edges 72a, 72b are straight and extend vertically. The vertical portion 72 is delimited vertically by an upper edge 72c.

[0110] To lock the upright 20 onto the shoe 18, proceed as follows.

[0111] The opening 40 of the shoe 18 allows the lower end of the upright 20 to be inserted inside it in its unlocked position as illustrated in [Fig.21].

[0112] The upright 20 is inserted into the shoe 18 by sliding it vertically from top to bottom until the upper edge 46b of the horizontal part of the slot is at the same height as the upper wall 26. In this position, the upright 20 remains axially separated from the lower wall 24 of the shoe. To facilitate the vertical positioning of the upright 20 relative to the shoe 18 in its unlocked position, the size of the opening 50 in the inner wall 32 is preferably adapted so that the upright 20 is in contact with this inner wall in the unlocked position. The inner wall 32 thus forms a stop wall.

[0113] When introducing the upright 20 into the shoe 18, the longitudinal edge 40a ([Fig.24]) of the opening can be used for the vertical guidance of the upright, and more specifically of the main face 20b.

[0114] In this unlocked position, the upright 20 can be freely moved vertically upwards relative to the shoe 18. In this position, the main face 20a and more generally the upright 20 remains at a distance from the longitudinal edge 40b of the opening and the finger 70 of the shoe.

[0115] Referring now to [Fig. 22], the shape of the opening 40 in the upper wall 26 of the shoe allows the upright to be rotated a few degrees around a vertical axis from its unlocked position to reach an intermediate position. In the illustrated embodiment, the transition from the unlocked position to the intermediate position is achieved by counterclockwise rotation. Alternatively, it could be possible to shape the opening 40 and arrange the finger 70 to allow the upright to move from the unlocked position to the intermediate position by clockwise rotation.

[0116] In this intermediate position, the upright 20 rests against the longitudinal edge 40b of the opening 40 of the shoe. The main face 20a of the upright rests against the longitudinal edge 40b. In this position, the finger 70 of the shoe projects inside the horizontal part of the slot 46 and is aligned with the vertical part 72. The width of the vertical part 72 of the slot is slightly greater than the width of the finger of the shoe. In this intermediate position, the upright 20 remains at a distance from the lower wall 24 of the shoe.

[0117] From this intermediate position, the upright 20 is moved into its locked position by sliding vertically downwards until it comes into contact with the lower wall 24 of the shoe. As illustrated in [Fig. 23], in the locked position, the finger 70 of the shoe protrudes inside the vertical portion 72 of the slot 46. The finger 70 is thus supported against the upper edge 72c of the vertical portion of the slot. Alternatively, the finger 70 could remain away from the edge 72c while still being housed within the vertical portion 72 of the slot.

[0118] In the locked position of the upright 20, clockwise rotation of the upright is blocked by the contact between the finger 70 of the shoe and the lateral edge 72a ([Fig. 24]) of the vertical portion 72 of the slot in the upright. Counterclockwise rotation of the upright is also blocked by the contact between the finger 70 of the shoe and the lateral edge 72b ([Fig. 24]) of the vertical portion 72 of the slot in the upright, and by the contact of the main face 20a against the longitudinal edge 40b of the opening. In this position, the upright 20 is rotationally fixed to the shoe 18.

[0119] Thus, in this embodiment example, to move from the unlocked position of the upright 20 to the locked position, it is necessary to provide for a rotation of the upright in the counter-clockwise direction and then a translation downwards relative to the shoe 18. Conversely, to move from the locked position of the upright 20 to the unlocked position, it is necessary to proceed with a translation upwards of the upright and its rotation relative to the shoe 18 in the clockwise direction.

[0120] In the illustrated embodiment, the slot 46 of the upright has, in addition to the vertical portion 72, the horizontal portion 47 to facilitate the insertion of the finger 70 of the shoe when moving the upright from the unlocked position to the intermediate position. Depending on the shape of the finger, it might be possible to omit the horizontal portion 47.
