| (54) | Arrangement for attaching light fittings to false ceilings |
| (57) The present invention refers to a perfected arrangement for attaching light fittings
and similar devices in false ceilings of the type which have a fitting (1) supporting
one or various lamps which are provided with a lower end (1.1) which is placed against
the lower surface of the false ceiling (2), with the rest of the fitting (1) penetrating
through a perforation (2.1) made in the false roof. The arrangement is provided with
at least two attachment devices on the periphery of the fitting, consisting of a vertical
threaded rod (3) with a lower operating head (3.1) and upper support part (3.2). The
device is characterised in that it is provided with a means of attachment (4) which
is axially displaceable by the threaded rod (3) when its rotation is blocked on activating
the rod (3). In an initial position the means of attachment is situated tangentially
to the fitting and in operative mode it is situated radially to the fitting, pressing
on the upper surface of the false roof.

OBJECT OF THE INVENTION
[0001] The present invention refers to a perfected arrangement for attaching light fittings and similar devices in false ceilings of the type which have a fitting supporting one or various lamps which are provided with a lower end which is placed against the lower surface of the false ceiling, with the rest of the fitting penetrating through a perforation made in the false roof. The arrangement is provided with at least two attachment devices on the periphery of the fitting consisting of a vertical threaded rod with a lower operating head and upper support part.
[0002] The device is characterised in that it is provided with a means of attachment which is axially displaceable by the threaded rod when its rotation is blocked on activating the rod. In an initial position the means of attachment is situated tangentially to the fitting and in operative mode it is situated radially to the fitting, pressing on the upper surface of the false roof.
BACKGROUND TO THE INVENTION
[0003] Various arrangements are known in the state of the art for attaching lighting fittings and similar devices to false ceilings.
[0004] An example is Utility Model U9900153 filed by the same applicant and which protects an arrangement provided with at least two attachment devices which include the following elements:
- a) a vertical threaded rod, with a lower operational head and an upper support point.
- b) A traveller fixed on the rod and able to move axially due to its thread which, when the rod rotates, prevents free rotation of the indicator;
- c) An upper clamping body dragged by the traveller movement and able to assume an initial position in which it is slightly extended parallel to the axis of the rod, and a second clamping position in which it extends, forming an angle with respect to the axis and presses on its lower free end against the upper surface of the false roof;
[0005] The object of the present invention is to provide a new attachment arrangement which improves the previous state of the art, obtaining a device which has fewer parts, which means a reduction in manufacturing time and costs, and which at the same time provides greater rigidity in attaching the device.
DESCRIPTION OF THE INVENTION
[0006] The present invention refers to a perfected arrangement for attaching lighting fittings and similar devices to false ceilings of the type which are provided with a fitting which supports one or various lamps and which has a lower border which is placed against the lower surface of the false ceiling with the rest of the fitting penetrating through a perforation made to this effect.
[0007] The perfected arrangement of the present invention is provided with at least two devices situated on the periphery of the fitting which are provided with a threaded vertical rod with a lower operating head and an upper support zone. The device is characterised in that it is provided with a means of attachment which is axially displaceable by means of the threaded rod when its rotation is blocked on activating the rod. In an initial position the means of attachment is situated tangentially to the fitting and in operative mode it is situated radially to the fitting and pressing on the upper surface of the false ceiling.
[0008] The means of attachment is of a length which permits its entry through the perforation in the false ceiling in its position, tangential to the periphery of the fitting.
[0009] In order to prevent free rotation of the attachment means the threaded rod is situated between two vertical walls emerging from the fitting so that when the means of attachment is situated in the position radial to the fitting through rotation of the rod, these lateral walls prevent rotation, causing the means of attachment to descend along the length of the threaded rod.
[0010] At least one of the lateral walls is provided in its upper zone with a cavity for housing the means of attachment when it is in a position tangential to the fitting.
[0011] The means of attachment consists of a "C"- shaped profile joined to the threaded rod through holes in their two extensions and the end which is furthest from the fitting has a section in its extension close to the false ceiling rotated at 90° in a downward direction.
[0012] For the upper attachment of the rod, a part provided with at least one bushing hole is used for inserting the upper end of the rod. This part is provided with two grooved ends antagonistic to other grooves in the lateral walls for the insertion and attachment thereof.
DESCRIPTION OF THE DRAWINGS
[0013] The present descriptive report is supplemented with a set of drawings which illustrate a preferred example which are, however, in no way restrictive of the invention.
[0014] Figure 1 is a perspective view of the arrangement for attaching light fittings in false ceilings in which the attachment element is in its first position.
[0015] Figure 2 shows a perspective view of the arrangement for attaching the light fittings in their attached position.
PREFERRED EMBODIMENT OF THE INVENTION
[0016] The present invention refers to a perfected arrangement for attaching light fittings and similar devices in false ceilings of the type which have a fitting (1) which supports one or various lamps and which is provided with a lower border (1.1) which is placed against the lower surface of the false ceiling (2) with the rest of the fitting penetrating through a perforation (2.1) made in the false roof (2), the arrangement of which is provided with at least two attachment devices on the periphery of the fitting consisting of a vertical threaded rod (3) with a lower operating head (3.1) and upper support part (3.2) characterised in that it has a means of attachment (4) which is axially displaceable by means of the threaded rod (3) when its rotation is blocked by activating the rod (3)which in an initial position (4) is situated tangentially to the fitting (1) and in operative mode it is situated radially to the fitting(1) and pressing on the upper surface of the false roof (2).
[0017] The threaded rod (3) is situated between two vertical walls (1.2, 1.3) emerging from the fitting (1) in this way preventing free rotation of the attachment means (4) when the threaded rod (3) is activated.
[0018] At least one of the lateral walls (1.2, 1.3) has a cavity (1.2.2) for fitting the means of attachment (4) when it is in its initial position, that is, tangential to the fitting (1).
[0019] The means of attachment (4) consists of a "C"- shaped profile which is long enough for its entry into the perforation (2.1) of the false ceiling (2) in its position tangential to the periphery of the fitting (1) and which is joined to the threaded rod (3) by means of bushing holes (4.1.1., 4.2.1) in their two extensions (4.1, 4.2) and the end of which has a section (4.2.2) of its extension (4.2) close to the false ceiling (2) which turns at an angle of 90a in a downward direction.
[0020] For the upper attachment of the rod (3) a part (5) provided with at least one hole is used for inserting the end (3.2) of the rod (3) with this part being provided with two grooved ends (5.1) antagonistic to other grooves (1.2.1, 1.3.1) made in the lateral walls (1.2, 1.3) for the insertion and attachment thereof (5).
