Description

Title of the invention: Device for fixing a drain pipe in a crawl space to a rod, for example a threaded rod. Technical field

[0001] The invention relates to the field of supplying equipment for plumbers, masons or other craftsmen, requiring the fixing of a drain pipe in a crawl space.

[0002] More broadly, the invention finds an advantageous application when it comes to fixing a drain pipe in a crawl space to a threaded rod under a slab or a false ceiling. Previous art

[0003] In the building sector, it is common to want to install pipes in a crawl space to ensure proper drainage of wastewater. These pipes are most often fixed under a false ceiling or a slab.

[0004] Pipes in crawl spaces need to be laid at a specific slope for the drainage of waste or wastewater. Several fixing methods exist to achieve this slope.

[0005] It is known to use, for example, metal rods or suspension wires associated with suspension or fixing collars, for example of the clamp type, pear clamp or fixing clip.

[0006] These hangers, or metal rods, must be cut to a specific and precise length to achieve a suitable slope. They are then fixed under the slab in ascending order of size. Finally, a suspension or clamping collar is attached to the lower end of these hangers or rods to accommodate the pipe in the crawl space.

[0007] This type of solution has the disadvantage of being complex to implement. Indeed, there are several implementation steps including cutting the rods to a given length, grinding the rods to make the thread take, the fixing step which must be carried out in a precise order and the step of securing the rod with the suspension collar. Description of the invention

[0008] One of the aims of the invention is therefore to remedy the problems of the prior art by providing a device for fixing a pipe in a crawl space which is of simple design, modular, while avoiding a multiplication of implementation steps which would increase installation costs.

[0009] Another objective is to provide a sanitary pipe fixing device that is adaptable and precisely adjustable, without compromising the fixing structure in its entirety.

[0010] Another objective is to be able to ensure the stability of a sanitary pipe fixing device, avoiding the risks of wear or fracture of the pipe.

[0011] For this purpose, a device has been developed for fixing a drain pipe in a crawl space to a threaded rod anchored under a slab or a false ceiling, the device being formed of a single monobloc piece, which gives it great simplicity of design and assembly.

[0012] To ensure a secure hold of the pipe on the rod, the fastening device includes means for snapping the drain pipe into place, comprising two elastic arms defining a C-shape. "C-shape" means any open shape that can be fitted around the circumference of the pipe. A U-shaped or polygonal shape could also be used without departing from the scope of the invention.

[0013] The fastening device comprises at least two first C-shaped parts, located on an external face of at least one arm, the first two C-shaped parts being coaxial and spaced apart from each other by a distance corresponding at least to the diameter of the rod, each first C-shaped part having a diameter and an opening adapted for the passage of the rod, the openings of the first two C-shaped parts being opposed to each other in order to allow the first C-shaped parts to be locked onto the rod by a quarter turn movement after the rod is engaged in the space between the first two C-shaped parts, and the axis of the C-shaped locking means being orthogonal to the axis of the first C-shaped parts.

[0014] The snap-on means, along with the initial C-shaped sections, allow for the quick, safe, simple, and efficient installation of a drain pipe. The C-shaped sections enable the device to be quickly attached to a pre-installed metal rod without the need to cut the rod to a specific size. The height adjustment of the fastening device, particularly to ensure the required slope, is achieved by screwing / unscrewing the device along the rod.

[0015] To improve stability, it may be considered to arrange the threaded rods in a staggered pattern along the drain pipe.

[0016] The C-shaped snap-on means, thanks to the two elastic arms, allow the evacuation pipe to be received and to adapt to different pipe sizes without difficulty.

[0017] In an advantageous embodiment, the device includes second C-shaped parts, similar to the first C-shaped parts, located on the other arm of the snap-on means, which have, for example, a diameter different from that of the first C-shaped parts, in order to adapt to different rod sizes.

[0018] Preferably, at least one of the branches, and preferably both branches, have an end curved inwards to come into contact with the pipe in order to hold the pipe firmly in place, and to adapt to different pipe sizes.

[0019] In a preferred embodiment, the curved end(s) of the branches have a convex transverse edge. This convex edge makes it possible to maintain a single point of contact with the drain pipe and to compensate for any misalignment of the devices along the pipe.

[0020] Advantageously, the branch or branches include an external rib formed in the space defined between the first C-shaped parts and / or second C-shaped parts, in order to exert a bearing force on the metal rod to facilitate the screwing / unscrewing operations of the device on the threaded rod.

[0021] For example, the external rib is transverse to engage in a thread of the rod when the latter is threaded, or longitudinal to exert pressure on said thread in order to facilitate adjustment of the position of the device along the rod by screwing / unscrewing the device.

[0022] In order to optimize screwing / unscrewing operations, the external rib is longitudinal and has a triangular section.

[0023] Advantageously, the first C-shaped parts and / or the second C-shaped parts include internal longitudinal ribs formed on an inner face intended to exert pressure on the stem, in order to secure it more firmly.

[0024] Preferably, the elastic branches have a convex internal surface to compensate for any misalignment of the devices along the pipe.

[0025] The device according to the invention also allows the drain pipe to be positioned as close as possible to the slab or false ceiling by attaching the device to the rod in such a way that the locking means are open downwards. This embodiment also allows a drain pipe to be fixed in a crawl space in a confined area.

[0026] Thanks to its one-piece design, its secure locking capabilities and its adaptability to different pipe and rod configurations, the fixing device according to the invention represents a practical and efficient solution for fixing pipes in sanitary drainage. Brief description of the drawings

[0033] With reference to figures 1 to 6, the invention relates to a device (1) for fixing a drain pipe in a crawl space to a threaded rod anchored under a slab or a false ceiling.

[0034] It is formed of a single monobloc piece, comprising snap-fit ​​means (2) for the drain pipe comprising two elastic branches (2a) defining a C shape. The elastic branches are configured to snap-fit ​​a pipe with a diameter of 100 mm, without this being limiting, which corresponds to the pipes commonly used for drainage in crawl spaces.

[0035] The device (1) also includes two first C-shaped parts (3), located on an external face of the branches (2a), the first two C-shaped parts (3) being coaxial and spaced apart from each other by a distance corresponding at least to the diameter of the stem, for example preferably between 20 and 30 mm.

[0036] Each first C-shaped part (3) has a diameter and an opening adapted for the passage of the rod, the openings of the first two C-shaped parts (3) being opposite each other in order to allow the first C-shaped parts (3) to be locked onto the rod by a quarter turn movement after the rod is engaged in the space between the first two C-shaped parts (3), the axis of the C-shaped locking means (2) being orthogonal to the axis of the first C-shaped parts.

[0037] In this way, the invention allows, by snapping several devices onto threaded rods, the fixing of a pipe in a crawl space, itself snapped between the two elastic arms (2a) of each device. The height adjustment of the fixing device, in particular to ensure the recommended slope, is achieved by screwing / unscrewing the device along the rod. The operation is simple and effective. In practice, the devices are fixed to the threaded rods with the elastic arms (2a) facing upwards to optimally support the pipe. However, it is possible to position a first device with the elastic arms (2a) facing downwards to allow the pipe to be positioned as close as possible to the false ceiling if space is limited. To ensure optimal stability, the threaded rods can be staggered along the drain pipe.

[0038] With reference to [Fig. 1], the second C-shaped parts (4) are similar to first C-shaped parts (3), and are located on the other branch (2a) of the ratcheting means (2).

[0039] With reference to [Fig.2], the second C-shaped parts (4) have a different diameter than the first C-shaped parts (3), in order to adapt to different rod diameters used by craftsmen, for example M6, M7, M8 or M10. For example, one side may have M8 and the other M6 / M7.

[0040] With reference to figures 1 and 2, the two arms (2a) have an end curved (5) inwards to come into contact with the pipe in order to hold the pipe firmly in place, and to adapt possibly to different pipe sizes.

[0041] Each curved end (5) of the arms (2a), and in particular the free transverse edge, has a convex profile (6). This convex profile allows the device to bear on the pipe at a point of contact and thus allows for a misalignment of the devices along the pipe.

[0042] Each arm (2a) of the snap-on means (2) includes an external rib (7) formed in the space defined between the first C-shaped parts (3) and / or second C-shaped parts (4), in order to further secure the attachment with the threaded rod, by exerting a bearing force on the rod held in the first C-shaped parts (3) and the second C-shaped parts (4).

[0043] The rib (7) located on each branch (2a) is for example longitudinal to exert pressure on said thread in order to allow adjustment of the position of the device (1) along the rod by screwing / unscrewing the device (1).

[0044] According to the embodiment illustrated in figures 4 to 6, the rib (7) has a triangular section so that the point of the triangle bears linearly against the rod when engaged in the C-shaped forms. This optimizes the forces and the thread of the rod digs and taps the point of the rib.

[0045] The first C-shaped parts (3) and the second C-shaped parts (4) include internal longitudinal ribs (8) formed on an inner face intended to exert pressure on the rod in order to ensure the immobilization of the device (1) and therefore its stability.

[0046] With reference to figures 1 and 3, the inner face (9) of the elastic branches (2a) and in particular their portion in contact with the pipe, is convex in order to bear on the tube in a single line of contact to tolerate misalignment of the devices along the pipe.

[0047] Preferably, and as illustrated in Figures 4 and 5, the C-shaped snap-on means (2) of the drain pipe include a rib (10) which runs along said C-shape to provide more rigidity.

[0048] In conclusion, the device (1) for fixing a drain pipe in a crawl space According to the invention, it offers a practical and efficient solution for fixing drain pipes. Its one-piece design, secure locking mechanism, and adaptability to different pipe and rod configurations make it an easy-to-use device (1) for building and industrial professionals.
