Description

DESCRIPTION

Quick mounting system for ceiling fans with downrod

TECHNICAL SECTOR

The present invention relates to a new quick mounting system for ceiling fans, and more specifically for fans of the type that include a rod that allows adjusting the distance between the ceiling and the fan.

The object of the invention is to provide a system that greatly facilitates the handling of cables and parts, significantly reducing execution and assembly times, all in a very simple way that does not require special skills.

BACKGROUND OF THE INVENTION

In the practical application of the invention, when installing a ceiling fan, it is common for it to include a metal structure that is screwed to the ceiling, and into which fits a kind of ball joint that terminates a strut or stem that emerges from the main body of the fan and that can be supplied in different lengths, to adjust the distance between the ceiling and the fan.

These elements must be covered by decorative covers, which significantly hinder the installation, cable connection, and general handling.

In short, the mounting methods for ceiling fans currently available require considerable skill and handling time, which has a very negative impact when they are installed by consumers who are not DIY experts, to the point of having to resort to professionals with the consequent additional cost that this entails.

EXPLANATION OF THE INVENTION

The proposed ceiling fan mounting system fully and satisfactorily resolves the aforementioned problem, based on a simple yet highly effective solution.

To this end, starting from the conventional structure of a ceiling fan, whether with fixed or folding blades, the invention focuses its characteristics on the fact that its stem is linked at the top to a piece or rosette that, in addition to presenting a function as an embellishment element, acts as a support element, so that this element on which the fan stem is supported is fixed to the ceiling through a support in an extremely quick and simple way.

More specifically, the ceiling mount has an inverted cylindrical cup-shaped configuration, the base of which includes a central hole for passing the fan's power cables, as well as a series of perimeter holes for screwing this piece onto the ceiling.

The vertical and perimeter wall of this cup has the particularity that it includes stepped recesses that after an initial vertical section extend into a lateral sector that determines a bayonet closure in which two protruding pins from the inner wall of the upper edge of the rosette that supports the stem and other elements of the fan fit by plugging and turning.

In this way, the coupling between the fully assembled fan and this support only requires a simple and quick maneuver of aligning the pins with the bayonet locking mouths and their corresponding rotation until said pins reach the end of the lateral travel of said guides.

However, before carrying out this maneuver it is necessary to connect the cables coming from the electrical installation of the house with the fan wiring, which is also accessed through the upper opening of the ceiling rose, cables that are previously passed through the inside of the stem.

To this end, and in accordance with another of the characteristics of the invention, it has been provided that the assembly is complemented by a rod in the shape of a with its middle branch elongated, whose upper branch is inserted into a hole provided in the ceiling support, while its lower branch is in turn inserted into a hole provided near the upper opening of the rosette.

This rod allows the entire weight of the fan to be supported and positioned far enough away from the fan support column to leave sufficient space to connect the aforementioned cables in a convenient and accessible manner. Once these cables are connected, the rod, being an accessory, will be removed, and the ceiling rose will then be bayoneted into the ceiling support.

Finally, it should be noted that the device will include at least one safety screw, linking two threaded holes facing each other between the ceiling support and the support column in the coupling position between these parts, to prevent them from being accidentally dislodged.

This results in a very simple and quick ceiling fan mounting system that requires a lower level of skill when performing this type of installation, making it accessible to most of the general public.

BRIEF DESCRIPTION OF THE DRAWINGS

To complement the description that follows and to aid in a better understanding of the characteristics of the invention, according to a preferred embodiment thereof, a set of drawings is included as an integral part of said description, in which, for illustrative and non-limiting purposes, the following has been represented:

Figure 1 shows a perspective view of the ceiling support that participates in a quick mounting system for ceiling fans made in accordance with the object of the present invention, a support on which the accessory rod in the shape of a “C” is attached.

Figure 2 shows a profile view of the assembly in Figure 1.

Figure 3 shows a top perspective view of the rosette that supports the fan through the corresponding stem associated with this piece.

Figure 4 shows a perspective view of the main body of the fan in its initial assembly state, supported by the "C" rod fixed to the ceiling support, creating enough space to manipulate the fan's power cables.

Figure 5 shows an enlarged detail of the set in Figure 4.

Figure 6 shows, finally, an exploded view of the system of the invention, including the safety screw that is finally installed, as well as the key for operating said screw.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the figures described, it can be observed how the quick assembly system of the invention is applicable to all types of ceiling fans with a rod, such as the one shown in figure 6, in which a main body (1) is linked to folding blades (2), and which has lighting means (3) at its lower base, although the invention, as mentioned, is equally applicable to fans with fixed blades, with or without lighting means.

Well, the main body (1) of the fan will preferably come from the factory assembled, except for its stem (20) and rosette (4), to minimize packaging space, assembly which is quick and easy.

Once this maneuver has been carried out, the fan can be easily handled as a one-piece unit, complemented by a ceiling support (5), shown in detail in figures 1 and 2.

The ceiling support (5) has an inverted cylindrical cup-shaped configuration, the base of which includes a central hole (7) for passing cables from the house installation, intended to electrically power the fan, as well as a series of perimeter holes (6) for screwing this piece onto the ceiling.

These holes can be either round or elongated, which further facilitates the installation of the support, which is materialized in a light and easy-to-handle piece.

According to another feature of the invention, on the vertical perimeter wall of the ceiling support (5) at least two stepped recesses are established which, after an initial vertical section (11), extend into a lateral sector (12) determining a bayonet closure in which two studs (17) emerging from the inner wall of the upper edge of the rosette (4), visible in figure 5, fit by plugging and turning.

These studs are intended to fit into respective seats (13) provided in the side sector (12) and include threaded holes (16) complementary to respective holes (14) provided above the seats (13), for the passage of at least one safety screw (15) operated by a key (18).

However, as previously stated, this simple maneuver must be preceded by the connection maneuver between the fan's power cables, housed in the ceiling rose (4), after passing internally through the stem (20) and the cables of the house installation, which protrudes through the central hole (7) of the ceiling support (5).

For this purpose, the system is intended to be complemented by an accessory piece, specifically a “C” shaped rod (8) with an elongated middle branch, intended to link the ceiling support (5) and fan in a sufficiently separate manner to allow the handling of the cables in a comfortable and safe way, according to the position shown in figure 4.

More specifically, the upper branch of the “C” rod (8) will be inserted into a housing (9) provided on the roof support, while the lower branch of said rod will be fitted into a support hole (10) provided in the rosette (4), as can be seen in figure 5.

This allows defining a suitable workspace to connect the cables together, after which the "C" rod (8) will be removed and the studs (17) will be inserted into the opening or initial vertical section (11) of the bayonet closure, and then the column will be turned until said studs are fitted into the seats (13) of the side sectors (12), in which position at least one safety screw (15) will be applied to prevent relative rotation between the roof support (5) and the rosette (4).

Based on this structure, it is possible to install a ceiling fan without the need for third-party help, with a minimum of tools, in a minimum of time and without requiring special skills.
