Definitions
- the present description generally relates to building surface products, for example, panels and connectors adapted to form a building surface.
- Construction panels for example plasterboard, are used to construct surfaces such as walls and ceilings within a building. Such building surfaces are formed by attaching building panels to a support structure.
- the support structure comprises a plurality of framing elements which are connected to each other and also to at least one of the permanent wall, floor or ceiling of the building.
- the panels are attached to the framing elements.
- Framing members may be rails, stiles, or other profiles that include a configured surface for attaching a construction panel. Framing members may be c-shaped.
- a "c-shaped" framing member is defined as formed to include a pair of flanges substantially parallel to each other and connected substantially perpendicularly at their base by a web, with the pair of flanges having returning edges directed toward each other. the interior substantially parallel to the veil.
- the framing elements are suspended from the permanent building ceiling by rods.
- Connectors are used to connect the rails to the rods. It may also be necessary to connect two framing members together in line, effectively extending the length of the framing members.
- These connectors comprise two parallel plates, each plate having a shape with slots and designed to be inserted into the hollow part of a c-shaped rail. These two plates are joined together by a junction plate, said junction plate being arranged to fix the rod.
- the installation of the connector is carried out by inserting said connector into the hollow part of a rail.
- the insertion is made so that the parallel plates extend along the length of the rail.
- the connector must be put rotating to be placed in its final position so that the parallel plates of the connector are blocked in the rail.
- the disadvantage of this embodiment is that a significant force is required to position the connectors in the rails and current connectors have a very low tolerance for error. This is because once the connector has been positioned inside the rail, it is difficult to slide them along the rail to adjust their position. This can make installation difficult because in order to avoid stressing the suspension, the connector must be directly under the permanent ceiling position where the rod will connect.
- the present invention provides a method for solving the aforementioned drawbacks and provides a connector which is simpler to use.
- the present invention relates to a connector configured to be inserted into the hollow part of a framework element and to support said framework element, characterized in that the connector comprises a main plate from from which two extension plates extend, said extension plates comprising an elastically deformable material, the connector further comprises means for elastically deforming said connector whereby an application of force causes said connector to adopt a first position in which the extension plates are deformed to be closer together to allow the connector to be inserted into the hollow portion of the framing member and subsequent reduction in force causes the connector to adopt a second position in which the extension plates contact the framing member to secure the connector to the framing member.
- the framing element may be a rail.
- the extension plates are symmetrical to each other.
- the extension plates comprise a single part.
- the extension plates comprise at least two parts extending in opposite directions, a first part extending from the main plate and a second part extending from the first part.

- the base 41 is attached by screws, bolts, anchors, adhesive or other suitable fasteners to the ceiling or permanent wall or to a structure attached to the ceiling or permanent wall.
- a connector or fitting 43 is designed to be simpler than the connector of the state of the art.
- a connector 43 according to the present invention is shown in Figure 3.
- This connector 43 comprising a main plate 430 in which the rod is fixed.
- the rod 42 is screwed onto the main plate 430 through a hole 431 or through a tube having a thread.
- Said connector further comprises two extension plates 432 or wings.
- These expansion plates 432 are preferably symmetrical, but alternative examples of the invention may have non-symmetrical expansion plates 432.
- the shape of the expansion plates 432 is configured such that at least one point of each extension plate is in contact with the interior of the framing member. This allows Connector 43 to hold the framing element.
- each extension plate 432 comprises two parts.
- a first part 4320 extending from the main plate 430 and a second part 4321 extending from the first part.
- the shape of the second part allows said part to be in contact with the framing element.
- the first one part and the second part extend in a different direction.
- the expansion plates are symmetrical.
- the second part can be a curved part as seen in Figure 3 or a linear part comprising an extension blade 4322 extending towards the framework element as seen in Figure 4.
- This blade extension 4322 can be an attached element as seen in Figure 5 or can be formed by deformation of the extension blade as seen in Figure 6.
- each extension plate 432 comprises only a part, a single part, extending from the main plate as seen in Figure 7.
- the main plate 430 further comprises a hole 431 or a tube 433 having a thread into which the rod is inserted to be screwed.
- the main plate 430 is thus arranged to be suspended by said rod.
- the single part can be a curved part as seen in Figure 7 or a linear part comprising an extension blade 4322 extending towards the framing element as seen in Figure 8.
- the extension blade 4322 is used to be in contact with the framework element 2, in particular with the flanges of the C-shaped framework element as seen in Figure 4.
- the curved extension blades 4322 may comprise a groove or slot 4323. This groove or slot 4323 is used to cooperate with the framework element 2 to block the connector 43 in said framing element. This slot can take different shapes depending on the configuration of the connector.
- the slot is open as visible in Figure 4.
- This open slot is preferably used for a connector which is sized so that the main plate bears on the profile.
- the connector finds itself inserted in the profile by the main plate and the slots 4323.
- the slot has a C-shaped profile as visible in Figure 14. This C-shaped profile then includes a space allowing a portion of the profile to slide into it. As each extension blade includes a slot in C, the connector is fixed to the profile by these C slots. This second embodiment makes it not obligatory to have a connector sized to be supported on the profile by the main plate.
- the connector 43 is arranged to allow elastic deformation to simplify use.

These tabs are arranged at the level of the free ends of the extension plates 432. These tabs or ears extend from the free ends of the extension plates 432. the tabs of the two extension plates extend to diverge from each other.
- the connector With these tabs and the ability of the connector to deform elastically, it is possible, for the connector, to present at least two positions or states, as seen in Figure 9.
- a first state called release state
- the connector In a second state called installation state, the connector is subjected to a force.
- the operator uses the tabs of the gripping means as pliers so that the two extension plates of the connector are deformed so as to be brought together.
- the tabs 4350 we then understand that the operator directly applies a force on the gripping means, the tabs 4350. In this case, the connector becomes narrower so that said device can be inserted into the framework element.
- the steps for connecting the connector to the framework element are: - applying a force to the connector 43, using the gripping means, so as to place the connector in an installed state, and thereby reduce the friction between the connector and a framework element so as to to allow the connector 43 to be positioned inside a framework element 2;
- the connector 43 is designed to be a profile as seen in Figures 12 and 13.
