Description

Title of the invention: Cast iron radiator mounting assembly technical field

[0001] The present invention relates to the field of systems for fixing a cast iron radiator against a wall.

[0002] An advantageous application of the present invention lies in fixing a cast iron radiator against an old wall, or a cinder block or hollow brick wall with insulating lining - plasterboard. Previous art

[0003] Various systems for fixing a cast iron radiator to a wall are known from the prior art. A cast iron radiator has considerable weight, requiring a secure, solid, and reliable fixing support.

[0004] A first solution in the prior art consists of using wall-mounted fixing brackets.

[0005] These brackets are presented for example in the form of thick plates provided with a wall fixing plate at one end, and a hollow made in the plate at the other end, so as to accommodate the cast iron radiator manifold.

[0006] The plate of these consoles is provided with holes, so as to screw the fixing console to the wall.

[0007] This first solution, even though it can support the considerable weight of the cast iron radiator, requires that the brackets fixed to the wall be perfectly aligned on a horizontal plane. Furthermore, the mounting plate's holes are subject to wear, compromising the alignment and stability of the cast iron radiator.

[0008] This first solution is also unreliable when you want to fix the cast iron radiator on an old wall, or on a lined wall.

[0009] A second prior art solution consists of using feet to support the weight of the cast iron radiator from below.

[0010] This second solution, whether coordinated with the first solution or not, is also unsatisfactory, as it is equally ineffective in compensating for misalignment of the brackets on the wall when the radiator is mounted. Furthermore, these feet are generally not fixed to the floor, leading to a risk of instability, or even of the cast iron radiator falling.

[0011] The two solutions presented above also do not allow adaptation to possible defects in the wall and / or floor, nor to the manufacturing tolerances of said radiator. Description of the invention

[0012] One of the aims of the invention is therefore to remedy the problems of the prior art by proposing a system for fixing a cast iron radiator which is safe, simple, effective, and which makes it possible to resolve the disadvantage relating to possible defects in alignment of the wall fixings of the cast iron radiator.

[0013] To this end, a wall-mounting assembly for a cast iron radiator has been developed, the cast iron radiator comprising a cylindrical upper manifold, the wall-mounting assembly comprising: - two primary rods, each comprising a first threaded end intended to be screwed into a primary anchor bolt inserted into a hole in a wall, and a second end comprising a cradle intended to support the cast iron radiator manifold, with the primary rod extending perpendicularly to the manifold and to the general plane of the cast iron radiator; and - two primary anchor bolts, each intended to be inserted into the hole in the wall.

[0014] The fastening assembly is characterized in that a cradle base of at least one primary rod includes a tapped through hole, and a leveling screw inserted into the tapped through hole, so as to adjust the contact height between the cradle base and the manifold.

[0015] In this way, it is possible to fine-tune the height of the manifold, and therefore of the cast iron radiator, to ensure that the radiator is perfectly parallel to the floor. By doing so, the pressure forces exerted by the manifold on the two cradles of the two primary rods are similar, the radiator is held in a balanced position, and no support point is subjected to more stress than the other, while ensuring secure fixing of the radiator in any type of wall, whether new, old, or lined. Thus, if there is a misalignment of the primary rods fixed to the wall on a horizontal plane, the leveling screw allows this problem to be corrected by restoring the radiator to a level position.

[0016] Preferably, the second end of the primary rod includes a hexagonal recess, so that screwing the rod into the wall, as well as installing the fixing assembly, are facilitated.

[0017] Preferably, the primary rod has a diameter of 14 mm and a length between 160 mm and 300 mm. These dimensions allow for secure attachment to the wall, whether it is an old wall or a wall made of concrete blocks or hollow bricks.

[0018] Preferably, the fastening assembly also includes: - two secondary rods, each comprising a first threaded end intended to be screwed into a secondary anchor bolt inserted into a secondary hole of a wall, and a second end comprising an orthogonal plate intended to rest against a lower part of the cast iron radiator; - two secondary anchor bolts, each intended to be inserted into the secondary hole in the wall.

[0019] These two secondary rods and these two secondary anchor pins make it possible to stabilize the lower part of the cast iron radiator by forming a support.

[0020] According to a particular embodiment, the cradle is fixed to the second end of the primary rod by a weld point.

[0021] According to a preferred embodiment, the leveling screw is of the butterfly screw type, or of the set screw type so as to facilitate screwing into the tapped hole. Brief description of the drawings

[0031] The invention relates to a fixing assembly (1) for a cast iron radiator (2) according to the invention, as illustrated in figures 1 to 9.

[0032] This fixing assembly (1) for a cast iron radiator (2) comprises at least two primary anchor bolts (3) to be inserted into a wall (4), and two primary rods (5), one end (6), having a thread (61), intended to be inserted and screwed into these primary anchor bolts (3), and the other end (7) intended to support a cylindrical manifold (8) of a cast iron radiator (2). The cast iron radiator (2) typically corresponds to a cast iron radiator (2) with a thickness of 100 mm or 150 mm, provided with an upper cylindrical manifold (8).

[0033] This fixing assembly (1) is particularly suitable for old walls (4) or walls with an insulating lining and plasterboard (9).

[0034] The primary rods (5) have a diameter of 14 mm, and the primary anchor plugs (3) have a diameter of 18 mm. The length of the primary rods (5) is between 160 mm and 300 mm, to be chosen according to the thickness of the wall lining (4).

[0035] In practice, a primary rod (5) of 160mm is indicated for an old wall (4), a primary rod (5) of 200mm for a wall lining (4) of 70mm, a primary rod (5) of 240mm for a wall lining (4) of 110mm, and a primary rod (5) of 300mm for a wall lining (4) of 170mm.

[0036] Optionally, the primary rods (5) may have a length between 350mm and 400mm, for certain particular wall lining thicknesses (4) or for very old walls (4).

[0037] These dimensions of the primary rods (5) thus allow an expansion over several cells of the concrete block or brick of the wall (4) in which they are inserted, resulting in a strong hold of the fixing assembly (1) to the wall (4).

[0038] In order to support the manifold (8), the second end (7) of the two primary rods (5) includes a cradle (10), advantageously in the form of a receiving base in the shape of an arc or semicircle, so as to fit the external surface of the manifold (8) and adequately support the weight of the cast iron radiator (2). The cradle (10) is secured to the second end (7) of the primary rod (5) by a weld point (71).

[0039] The diameter of a semi-circular cradle (10) is preferably 55mm.

[0040] The base of the cradle (10) of one primary stem (5) among the two, or even of both, is provided with a through threaded hole (11), which also passes through the second end (7) of the primary rods (5). This threaded hole (11) is intended to receive a leveling screw (12).

[0041] The installation of the fixing assembly (1) is carried out as follows: a hole (13) is drilled in a wall (4), then the primary anchor plugs (3) are inserted into the wall (4), through the holes (13) drilled in the wall (4). The primary rods (5), in the form of screws, are screwed into the primary anchor plugs (3) using a hexagonal recess (14) provided on their other ends (7), by means of a suitable wrench (72).

[0042] When the manifold (8) of the cast iron radiator (2) is positioned in the recess of the cradle (10), its height above the floor can be adjusted by screwing the leveling screw (12) into the threaded hole (11), which allows the radiator (2) to be leveled in order to compensate for any misalignment of the rods fixed to the wall on a horizontal plane. The gap between the wall of the manifold (8) and the bottom of the cradle (10) is thus fine-tuned according to the user's needs for perfect alignment of the cast iron radiator (2) relative to the horizontal. The tightening of the leveling screw (12) is made easier when it is in the form of a wing nut.

[0043] The assembly (1) also includes two secondary rods (15), intended to be inserted into two secondary anchor bolts (16), these secondary anchor bolts (16) being inserted into the wall (4). These secondary rods (15) have a diameter of 7 mm, and the secondary anchor bolts (16) have a diameter of 10 mm.

[0044] These secondary rods (15) are provided, in a similar manner to the primary rods (15), with a first threaded end intended to be inserted and screwed into the secondary anchor pins (16).

[0045] The second end of the secondary rods (15) are provided with plates (17), so as to be able to form a support in the lower part of the cast iron radiator (2).

[0046] When the secondary rods (15) are installed in the secondary anchor plugs (16) inserted in the wall (4), only a portion (18) with a dimension between 20 and 25mm remains outside the secondary plug (16), so as not to damage any plasterboard (9) placed as a lining on the surface of the concrete blocks or bricks of the wall (4).

[0047] The primary (3) and secondary (16) pegs are ideally made of nylon polyamide 6 and have anti-rotation wings (19), and have a length between 160 mm and 300 mm. The primary (5) and secondary (15) rods are ideally provided with a white zinc-plated finish.

[0048] The dimensions of the primary (3) or secondary (16) dowels are particularly suitable for old walls (4) or walls (4) with a lining, as shown in the following illustrative examples: - for an old wall (4), a hole (13) is drilled to a depth of 170 mm. A 160 mm plug (3, 16) is inserted with an effective anchoring depth of 130 mm; - for a wall (4) with a lining thickness of 70mm, a hole (13) is drilled to a depth of 210mm. A 200mm dowel (3, 16) is inserted into it with an effective anchoring depth of 130mm, the effective anchoring depth corresponding to the portion of the dowel (3, 16) actually inserted into the wall (4) by disregarding the maximum thickness of the lining (20) of the wall (4); - for a wall (4) with a lining thickness of 110mm, a hole (13) is drilled to a depth of 250mm. A 240mm anchor (3, 16) is inserted with an effective anchoring depth of 130mm; - for a wall (4) with a lining thickness of 170mm, a hole (13) is drilled to a depth of 310mm. A 300mm anchor (3, 16) is inserted with an effective anchoring depth of 130mm.

[0049] The effective anchoring depth of the dowels (3, 16) is therefore preferably 130mm, ensuring a strong hold of the fixing assembly (1) of the cast iron radiator (2).

[0050] It follows from the above that the invention does indeed provide a fixing assembly (1) for a cast iron radiator (2) against a wall (4), particularly suitable for old walls (4) or walls (4) with an insulating plasterboard lining (9), with a capacity to level the cast iron radiator (2) relative to the horizontal.
